I'll keep you updated on what the owner decides to do! I sent it back to him today and he'll be looking into possibly having it repaired by a store with equipment needed to re-solder GPUs, etc. I didn't see any SMDs - including MOSFETs - heat up in our tests, otherwise I would have sought a donor board. Also, the suggestion about trying an external graphics card via Thunderbolt was a great one - unfortunately didn't have one on hand. Will order for the future! :-) Thanks for watching!
My only desperate attempt would be heating up the GPU hoping for it to get re-balled like the oven trick. You'll need protection from the heat going anywhere else. Was always fun to put your old Xbox 360 in a suitcase running to get the GPU alive again.
I have the same laptop and something similar happened to me but it was because of switching ram sticks. I dont know if CMOS reset is the same thing as what I'm gonna suggest if it is sorry. For me disconnecting the battery, holding down the power button for 30s~ fixed the problem.
This is a good intro for a collaboration with Louis Rossmann and you can become the Non-Apple repair guy!!! To be honest, I think your channel is morphing from a "here are the benchmarks" to a really good pc cleaning and repair channel. I say go for it.
Yeah I like whats happened and I think it's the result of the Covid situation last year, it morphed out of necessity. A lot of businesses had to change how they did things and its the sign of a good business owner that they can adapt, move on and survive in tough times. Plus it's also really entertaining to watch and I'm enjoying them :)
he would need to learn how to fix pcs first though. taking them apart is not that interesting. Although most shops do like to hire someone to disassemble lap tops and give the board to the tech to fix.
The machine for removing the GPU is crazy, not sure if you can do it safely with a heatgun, but it got on the board somehow, and that's how the c razy machine does it... (just very, very precisely Linus has a vid with Rossman where he shows it off.)
I work on a lot of laptops ... something I noticed when you took off the heatsink, he repasted with Kingpin KPX blue thermal compound--I would venture a guess that he tried re-pasting with Thermal Grizzly Conductanaut liquid metal thermal compund prior to Kingpin, and that shorted out the GPU chipset. Side Note: Kingpin KPX thermal compund is awesome for laptops. My suggestion is get into the BIOS by pressing the NOVO button with a SIM removal tool or paper clip--the BIOS uses the Integrated graphics and not the GPU, since the Y740 is an Intel Coffee Lake CPU with integrated graphics--this may offer some options for troubleshooting since the display should work at that point on integrated graphics. Otherwise, try unplugging battery and booting on Lenovo high watt power cord, like Troy Henry mentioned below.
Owner here: I bought the laptop as it is, there was no liquid metal used whatsoever. However when it gets back to me, I will take a look and see if there are any corrosion marks from liquid metal. I bought this laptop from a reviewer.
The way I "fixed" a laptop like this before was to find someone who had the same model and walk through the bios blind. We used the laptop with a working display to track the buttons I needed to push in the bios of the laptop without the working display. I was able to make the igpu the main one, rebooted it, and have used it since with no issues(aside from the dead discrete gpu that's just chillin on the board unused).
Hey Greg I have been LOVING the Fix or Flip and also the PCDC series! I love watching you bring old hardware back to life! Especially when you deep clean them. Its a nice change rather than just seeing people build computers with unattainable hardware especially graphics cards. I rather watch hardware be cleaned and fixed right now :P
@@mccalejk2 Blame these laptop designers they don't exactly make it easy for us to fix even if he had gotten it to switch to the Integrated graphics it still wouldn't have been "fixed" it wouldn't be playing games anymore fr
Greg, I know this might sound little crazy or very unlikely, sometimes backlight LED can go bad. Have you tried shinning a light near the LCD pannel while it's on? I notice it does shuts off when you press the power button, like going to shutdown or sleep mode. Also I've red some of the comments saying, "try using a m.2 to PCI-E adapter with desktop GPU, which is a good idea to diagnose if the CPU/APU still works but not the DGPU! Also I have you tried using the "FN+Screen" button to switch default screen, like if you want to have extended, duplicate or just show second screen (I know you can't see thes screen but it's worth a shot) Anyways I like this series of troubleshooting Computers from viewers near you, Keep up and good luck bud!
Fix or Flop is a great series, i am learning a lot from this series because of the wide range of configurations that come to you. This laptop one is very interesting.
I would have started with hooking it up to the LAN and see if it appears on the router. That way, you'll know if it is booting up. Yes, systems can boot up with a defective GPU, depending on where the issue lies exactly. Especially laptops which use some form of hybrid graphics, like you talk about. Btw the FLIR is a great addition to the kit!
Owner here: this is something I did not think of. I appreciate the suggestion. When it arrives back to me (it is on the way) I will try my best to update you if the laptop shows up on the router's app.
@@12349goku It's been a while ago but I've even seen a similair issue with an HP Zbook where the M.2 SSD was defective. This would cause the system not to POST or display anything. Try removing all non-essential devices. HDD, SSD, WAN card, battery and just run it off of wall power.
I’d like to add a note: there is a display cable that runs around the bezel of the monitor of the laptop. My Asus laptop did the SAME thing. If you reconnect the cable between the monitor and the keyboard you should be fine.
That could be it. reseating the display cable almost always solves the problem if the GPU didn't die. However the GPU should still get power even if the display cable is disconnected and there was no heat coming from it on the FLIR image.
I use to own a computer store and work on these things all day. Sager, Asus ROG (my favorite), Alienware, MSI, even HP gaming laptops. Usually the culprit was cold or cracked bga joints under the chip, where it got hot enough to slightly melt the lead free solder and cause one of the 500 little connections to lose continuity. Usually preheating the bottom for 10 minutes and reflowing the chip with kester 951 and a large enough nozzle would resolve the issue. I want to say it was 90% effective. So the chip may not be dead, more/less disconnected. The ones that didn't come back to life were sent out to L2 Computer in Brooklyn NY. They have a very expensive automated IR bga solder rework machine. They're usually pretty cost effective as well. If the laptop hasn't been sent to anyone else give them a try.
Great playlist! I'm new to building PCs (since 2019) but love to constantly learn more about troubleshooting and stuff that I hopefully won't run into in the future. Looking forward to more of this playlist!
I have been a laptop user since 2008/2009 so I'm really grateful to watch this. I've only done my own servicing once to my previous laptop and put simply, it was arduous, and nerve wracking.
I own a Clevo Sager P775TM1-G and I love that I can replace both the CPU and GPU if they were to fail on me. Yeah the graphics card module is expensive to replace, but it is still better than sending it in and paying way more to get it repaired when you're out of warranty.
One way to possibly fix it is to bake the motherboard at 200deg C for 10 minutes with the GPU/CPU Chips facing upwards. Do this at own risk, good ventilation is necessary as the smell is quite intense. This process allows the solder to soften enough to repair any minor cracks that may have been caused by the laptop overheating. Common problem with gaming laptops in general. Fixed 2 old laptops with graphics issues like this
IBM technician here! Your laptop skills are suprisingly good. If there is a discrete GPU it will probably be broken every time, no matter if its via slot or soldered into the board. This model would need a new planar. This model ive only swapped hinges to so its not a terrible one. Not that many businesses get gaming laptops, but some people pay for the best warranty that sends me to their house. :x
My 2010 Toshiba lappy died when I loaned it to someone who had a habit of putting it on bedding and blocking the airflow. Definitely a reball scenario. Back then I could have sent it to NYC for $125 and they said would include an updated graphics chip. I didn't do it. I looked into the DIY reballing a la XBOX 360 but never did it. I'm doing the oven thing right now, I'll keep yall posted.
I have the same laptop, but usually when mine doesn't boot, i can press the Novo button and it brings up options for BIOS Update, Setup, Normal Boot and stuff like that. It's a pin hole button near the right side power LED, kinda like a reset button. In Setup, there's an option to disable the discrete GPU, if that worked then definitely a problem with the GPU lol @Greg Salazar
You may have done this off camera, but I didn't hear you mention it. I was surprised you didn't try to boot it up with no SSD, HD, or Wifi card installed. I've seen so many times a simple short of some type on one of the removable components that causes there to be no video out. Not a good sign with the GPU showing no heat though. I think you nailed it.
My dream is always building a compact desktop rig that I could bring everywhere (because I'm a nomad stage operator that'd control broadcast and dmx system). DIY Perks has done this.
In Norway we have an extended warranty other than just the manufacturing one. "PCs, computer components and expensive printers are expected to have a service life significantly longer than 2 years and will therefore have a complaint period of 5 years, cf. Consumer Purchase Act §27. Some parts in these products such as batteries and adapters are considered to be wear parts and will therefore not have a life expectancy of significantly longer than 2 years, these parts will therefore have a limited warranty period of 2 years." This is from the electronics store Power.
Had the exact same issue. It was the Dram slot. Had to move my single stick into slot b and bam picture came back. It guy I used removed all ram and booted without ram, screen lit up immediately but obviously wouldn’t boot without ram. But this is how he proved it was the ram slot that was the issue.
Although might not be easy, you could try blind running into the bios by using a reference Legion bios as a guide to figure the navigation/key presses to switch to IGPU. Saving and exiting will bypass the DGPU I guess? I'm not sure..but would've been worth some tries if its only a GPU issue.
@@VentusHarpus12 i was more thinking in the way that IF it would work, he than could activate the integrated gpu (the one in the APU/CPU) and see if it works
Send it to Luis in NYC. That guy is really good at diagnosing dead boards. From what I see it looks like the GPU is not getting solid contact to produce the image. I came across a dead Y740 with same problem after the RMA it was a bad GPU luckily the guy who bring it to me had warranty still. Get that external GPU my dude, it helped me figure out issues on many things.
another thing that can be done to verify that the pc is working with no display out is trying to connect it to the network, checking the IP which was assigned to the machine from the router and then using another pc or phone to try and take an RDP session (for rdp to work a password needs to be set for the account) if this works then you know for a fact that windows is loading and there is no issue there, then we can check all devices etc and maybe get more information.
18:18 Back in 2000, after buying a 20Gb HDD from a local pc repair shop, they wanted to charge me about 75USD to hook it up which involved unplugging the molex and IDE cable from my dead HDD and just plugging them to the new one. Also wanted to charge me an extra 50USD to reinstall the OS (Windows 98). It's a good thing I learned to tinker with computers prior to (and maybe bricked a few) because these place can/will extort people for more money. That's why I don't mind fixing or upgrading a friend's pc or laptop.
Man I was hoping you could get it fixed but you did everything you could. By the end of the video I was hearing the jingle that plays when someone loses a game in the Price is Right. Dun dun dundun wuhhh🎵
I found this series and I love it. Awesome of you to do it for free even though you are already making TH-cam money. Also awesome of you to occasionally toss in an upgrade for free here or there. Keep up the great content
Lol, fixing my MSI because greedy them forgot to ad the 2nd m.2 slot components. Just fixed the order I have with Digi-Key since 1 part was on backorder til Feb 2022, and I don't want to wait that long!
I think he should put in the old ram.. mine is the y740 17in but with the 8750h and the 2080 Max-Q and mine runs flawless. Don't know if the ram speed matters but the CPU is set for 2666hz and that kit is 3200hz. Even though you can't overclock in the BIOS, I think it's worth a shot.
Oftentimes, I've found that a dead hard drive or an SSD reporting weird numbers on its SMART can prevent a boot. In my opinion, you should have checked to see if it would boot without those devices connected, as they are high failure rate components.
I think that the dgpu is working fine. In my case, the dgpu stays at 0% untill a game or a program requires it to work. So, there is no power input in the dgpu, hence no heat. All laptops (excluding MacBooks) are smart enough to use either the igpu or the dgpu based on the workload. The the most probable issue here should be a capacitor, resistor, IC or a fuse.
MacBooks actually has this feature... like the Early 2011 17-inch MacBook Pros had 6000M graphics (I believe it is the 6750M, correct me if I am wrong) which were prone to crippling graphics failure whereby it artifacts when something GPU intensive launches. There were workarounds such as physically disabling the dGPU by shorting two pins to make it only work on the iGPU... this iGPU with a render-only GPU has been implemented for years and it became industry standard basically when putting discrete GPU's in laptops.
Fixing laptops is the worst, especially now that they need to be thinner and smaller. Everything is shoved into a tiny ass space then you have to be columbo to know where all the little ribbon cables are and then putting them back together... I mean it is nice of them to include all those extra screws so you have them when you put it back together.. oh wait those are supposed to go somewhere 😳
something else you can try in future that may save laptops. when i worked in a repair shop a lot of the time all we needed to do with laptops that were behaving like this was disconnect the mains and battery hold the power button in for 30 seconds reconnect all then a lot of the time it would boot again.
At the end of what Greg did, I would have got a volt meter out and look for the power rails coming up on the main board. You can also test for shorts on the power rails, which may lead to a shorted item.
So just a theory for the future on laptops, i think you could possibly unplug the display ribbon cable, and then attempt to power on with an external display. Maybe it would work because it would be the only display attached.
something weird with lenovo laptops i noticed working on 2 already is that clearing the CMOS (disconecting the small battery on board) will damage BIOS installation. So by clearing CMOS he might have introduced another issue.
A laptop guide, advices are pretty rare to find. Although, the component name for pc and laptop are the same, it quite different on how they are on a laptop.. I hope there's more laptop guide out there from the major pc youtuber... Great work on the vids Greg!!!
I have laptop with the same issue, it can be dead GPU or a burned mosfet or coil in GPU power supply side. You have to test the components there for short and if a lot of are shorted use the voltage injection methode starting at the Mosfet with 1.5v and 3 amps at the beginning and looking under thermal cam to find the shorted component. Mine was more complicated because two power lines were shorted together and produced a lot of heat on the CPU which I was thinking about a shorted CPU but I couldn't be because a shorted CPU doesn't heat up like this , so I found a coil which was making this issues and then in Graphic chip part there were two dead coils, by replacing those I was able to power up the laptop, it took me 6 months to diagnose it.
We need laptops to have more replaceable and upgradable components! This is totally possible. Instead of having one mainboard or motherboard, have 3 connected to each other. One for the CPU, one for the GPU, and one for the motherboard. It wouldn't even make the laptop any thicker!
we basically had or have this allready in some way. in short: to expensive. look what mxm gfx cards cost. we had replaceable cpus too but if its not a standard part, its expensive. if its standard, its not optimised for laptops. overall not worth the effort to make something what a fraction of the customers want.
That's why I use a lot of older mobile workstations and gaming laptops. Everything including the GPU and CPU are upgradeable and replaceable if something dies.
I find that most laptops also have a FUNCTION key combo to swap between native and external Display. take a look at the keyboard functions. and you should see display symbols with a / between them. try that while powered on and the external should turn on. Great videos. keep them up.
There's one thing you could have done and that is to connect an external gpu to the laptop by way of the wifi connector inside the laptop, they do make adaptors for this and at least you could see a screen to run further test
Owner here: I actually returned the laptop, because I had put it on credit, and was only looking for a temporary solution. I decided to use an old notebook for about a month before building a new pc I got some deals on. So a ~1200 laptop went down to a ~$500 pc. You are correct, I should not have been hasty in my financial decision there.
@@12349goku next time send it to somebody who knows what the hell they're doing. You need to send it to someone with a microscope and a soldering iron who knows what the hell they're doing. There's plenty of shops you can mail it to who could find and fix the issue quick and easy.
@@easley421 Yeah, any engineer could isolate the faulty component/s. I'm not convinced it's the GPU chip, I'd be using a simple multimetre to check to see if the chip is being powered at all. As this was left on all night it may be that a fault in an IC has led to it's failure or a power surge perhaps, most repairs on most electronic devices are caused by small inexpensive part failures the only problem is when that leads to other parts failing.
@@easley421 I sent it to geeksquad as stated before, and they did roughly the same as Greg, however my hopes were to have him make a video based on this about what happened to my laptop. If it was a software fix or able to boot to igpu even if the dgpu was dead, I would have been overjoyed and it would be a fantastic way to show those who go through the same. Even though it was unable to be fixed, I am not heartbroken. While I do not have any shops nearby, I will try to email some places to get a quote for reballing and component diagnostics, no replacement GPU, only smds if needed. If it doesn't work with a reball, I will unfortunately need to put it on the back burner or sell it due to lack of funds.
This is why I avoid laptops except a small one I use for working/internet access when I travel. I get some people don't have the room for a desktop or students who want to also have something they can use to do work on and take to lectures but if anything goes wrong and you have no warranty left you're stuck. Gaming laptops are also stupidly expensive compared to what you could buy for that in a desktop and if anything goes wrong with a desktop you can easily replace a part within a day and at most a couple hours work if you need to replace a motherboard depending on how quick you are at removing everything and putting everything back with the new motherboard.
I used to work at a computer shop years ago, and people brought in laptops ALL the time like this. If it’s not as simple as replacing a broken screen, I just told them to buy a new one. Parts + labor made it not worth it for the majority, since name brands charge up the wazoo if you aren’t “authorized”.
Send it to Louis !! Like Mr Doom said it would make a great collab for you! He has all the tools and experience with laptops. You can just mail it to him and do a follow up ep via Zoom
One diagnostic you missed was unplugging the CMOS battery to reset the BIOS. The GPU not generating heat doesn't mean it's dead, there's no reason for it to power up during POST. Laptops like this run off the iGPU and only spin up the dGPU when software calls for it.
Perhaps some insight from a former laptop tech for major vendor that rhymes with Bell (Visit small business, residential, large companies, government offices etc etc). Loved the troubleshooting process you went through. Looks like you checked most options in a logical order. Generally how something like this would be handled (if laptop is under warranty) is in the first instance, the customer would call the support line and work with the help desk operator in troubleshooting the issue. In most cases, when the issue can not be solved over the phone the help desk would send the job out to the technician in the area. In the job, they would "shot gun" a bunch of parts that may solve the issue. In this case, more than likely they would of sent out a mainboard, display cable and display screen and provided instruction to swap over the mainboard first and see if that would solve the issue. If not, then display cable, then display screen. Its requested this way so that if the issue is resolved after replacing the mainboard, the display cable and display screen can be sent back. The faulty mainboard is also shipped back. Unsure of what process is conducted back at the vendor, but I believe the mainboards are reconditioned / repaired. Now imagine you have 8-10 jobs lined up for the day. All with similar issues. All spread over town. Time is precious and due to SLA and deadlines, spending a lot of time attempting to troubleshoot issues onsite causes headaches with customers / calls from vendor asking where you are haha. Obviously as you become more experienced, you work faster etc etc. But there is always the spanner thrown in the mix with laptop jobs. It can be cut-throat at times. Sometimes a job might be a simple battery replacement (5min job), or could be a full blown rebuild, where the laptop is in a 1000 pieces (1hr+). And this is also conducted in the clients office, home, shop etc etc. Give me a desktop PC to work on any day! Long winded post. But great content Greg. Enjoy your work.
Usually the iGPU will be outputting to the in-built display by default, which it should be after resetting the CMOS. My guess is either the motherboard itself has a fault or the CPU has died (it's rare but can happen). I've had a desktop motherboard kill 3 different CPUs whilst troubleshooting... wasn't a good time, at least it was only 4th gen intel chips and not something newer, still a shame though.
Great video Greg. You've gotten my neurons firing about the solution for this. There is a new company, Framework, that makes notebooks with discrete parts that can be easily replaced like a desktop computer. Google the company's name as it's a new company. Ravi Peiris M.D.
Another reason for lower amount of warranty time for laptops is they account for the possibility of people traveling with them. Movement, jostling, potential to drop or spill things on it.
You're probably right, but I would have tried (at least) three more things: * Unplug the screen from the motherboard and use the external display only * Use different RAM, I'd expect you have some spare laptop RAM you can use for testing purposes even if you can't give it away in a repair. * remove and replace CMOS battery to reset BIOS (I know he said he cleared the CMOS but as you said at the beginning you need to test it yourself)
4:11 For some reason, having an upside down USB A port for power really bothers me. it was a good idea to check the Mini DIsplayPort as well as the HDMI port. They can be wired separately, with one of them still functioning off the iGPU. No such luck in this case.
This could be anything. Maybe for the next time unplug the screen of the laptop itself so you know it's not grounding anything. The screens have a small logic board under the screen that goes bad all the time. I would next desolder the BIOS chip and reflashed it with the latest Lenovo BIOS. Nice video though. Fixing laptops is really hit and miss like you said.
Where i work, we repair this such issue. Its usually chipset on the board issues. Needing to be resolder. here our charges are 300myr = 70 usd at minimum. At the end of the day, i kept telling customers, if you really want to game, just get a desktop.
I was always a fan of being able to game on the move, but this is the reason I converted from a laptop to a desktop even though I always bought laptops that had interchangeable gpus and cpus.
Usually if there's an iGPU and a dGPU in a laptop, the dGPU is only used when 3D games and applications are used, the iGPU is used for BIOS/POST, BOOT time, and Desktop/2D Even with a dead dGPU, it should still give a display from the iGPU (how do I know? had a laptop where the dGPU died, I could still use it, just not for games, web browsing was fine)
Might not be a fail dgpu. It could be a stuck value in NVRAM specially if MS Hybrid has been disabled. Simply remove the Battery, CMOS Battery and AC then press and hold the power button for 30 seconds. Then hopefully it will reset the NVRAM variables. MSI Laptops had the same issue with a MUX switch which required a BIOS/EC hard reset. You could even do it without taking the case off as well some laptops have a little pin hole button to which you just disconnect the PSU and hold in the pinhole button for 30 seconds. On MSI laptops with the MUX issue the dgpu didn't power on at all as well.
One possible thing to try and get a sinal out of it is a USB 3 docking station. Those come with their own gpu and dont have to rely on the internal gpu.
I had an Lenovo legion y520 : I updated the bios and after successfull install the laptop bootlooped 😅(1120€!) I turned it off (the screen says do not turn off or something like that)and powered it back on…it works😂😂😂 Keep up the good work dude👍
Just an FYI for the future, my laptop from 10 years ago has a bad battery and the computer tells you this when its booting up. It has a warning message while its booting from the bios screen, not sure what its called but the screen where you can press delete or whatever to get into the bios before it loads into windows.. so if its ever a issue with the battery it should tell you and you shouldn't have to guess..
The fact that is not making any beeps, means that it's a corrupt bios. Common practice on cases like that is too take out absolutely everything, main battery and bios battery included and short the batterys contacts, together with pressing down the power button for more than a minute. Then, power on the device without the ram and battery. Usually, after mounting the ram, it boots, even if it's really borked up, but if so, it will not work nonetheless, but hey, its a little win...
Most of these laptop have a reset hole, check the user guide to locate it, that what you should try first, before anything. For me the most common laptop problem is dead ram (I have no idea why) but I see you didn't try new ram, maybe both stick is dead, try cleaning the ram slot too I see that GPU is not heating, but I use many gaming laptop and they're using IGPU for booting to windows then the software will consider which graphics to use depending on your activities, so that GPU chip shouldn't heat at all when booting.
Black screens are known problems with Lenovo machines. I've fixed them before by going to the recovery menu during startup. Press f11 when it's booting and the screen turns back on. Or it might be f8, I can't remember now.
I would assume it’s the CPU itself , being it’s not using the IGP to display anything . I had recently had a desktop with IGP but was also using a DGP . The CPU bricked when overclocking , causing my GPU to turn on and get power , but wasn’t doing anything but moving the fans and nothing coming from output. It seemed to post but no output on any display. Replaced the CPU through warranty and fixed my Issue.
Maybe you could have tried an eGPU if you have one? Or that weird NVMe GPU that was hot a few months ago. Or an NVMe to PCIe adapter with a classic GPU.
Okay, this might sound stupid, but aren't laptop default bios configuration should go with the iGPU (since you need to enable NVIDIA Optimus in the bios to use it) if so, why not try to clear the CMOS to make the bios configuration its default?
I'll keep you updated on what the owner decides to do! I sent it back to him today and he'll be looking into possibly having it repaired by a store with equipment needed to re-solder GPUs, etc. I didn't see any SMDs - including MOSFETs - heat up in our tests, otherwise I would have sought a donor board. Also, the suggestion about trying an external graphics card via Thunderbolt was a great one - unfortunately didn't have one on hand. Will order for the future! :-) Thanks for watching!
@@rickysargulesh1053 nice
Welcome for watching
My only desperate attempt would be heating up the GPU hoping for it to get re-balled like the oven trick. You'll need protection from the heat going anywhere else. Was always fun to put your old Xbox 360 in a suitcase running to get the GPU alive again.
I have the same laptop and something similar happened to me but it was because of switching ram sticks. I dont know if CMOS reset is the same thing as what I'm gonna suggest if it is sorry. For me disconnecting the battery, holding down the power button for 30s~ fixed the problem.
I was looking at some reviews of the same type of RAM that he had installed. Lots of other people were having issues, could be a contributing factor?

My suggestion is get into the BIOS by pressing the NOVO button with a SIM removal tool or paper clip--the BIOS uses the Integrated graphics and not the GPU, since the Y740 is an Intel Coffee Lake CPU with integrated graphics--this may offer some options for troubleshooting since the display should work at that point on integrated graphics. Otherwise, try unplugging battery and booting on Lenovo high watt power cord, like Troy Henry mentioned below.
Replying to this so that hopefully Greg sees it!
Liquid metal is everyone's worst fear especially if you are a PC or PS5 owner trust me
Owner here: I bought the laptop as it is, there was no liquid metal used whatsoever. However when it gets back to me, I will take a look and see if there are any corrosion marks from liquid metal.
I bought this laptop from a reviewer.
@@12349goku Is there a display off/presentation mode function key? Sometimes that gets toggled somehow and leaves you with a blank screen.

We used the laptop with a working display to track the buttons I needed to push in the bios of the laptop without the working display.

That would pretty much be the only way it is kind of weird though the IGP is not kicking in when the DGP fails.
i was thinking the same thing! ran to the comment's to see if anyone else suggested it.
Would be more convenient if you could find the videos of the same model online.
Your approach is so honest, it encourages us, the viewers to atleast do basic troubleshooting ourselves. Way to go man...hugely underrated stuff here.
Hey Greg I have been LOVING the Fix or Flip and also the PCDC series! I love watching you bring old hardware back to life! Especially when you deep clean them. Its a nice change rather than just seeing people build computers with unattainable hardware especially graphics cards. I rather watch hardware be cleaned and fixed right now :P
Glad you like them! More on the way.
ooo we finally got a laptop on the series :D this'll be really interesting
Thank gosh it was an actually decent laptop that was easy to take apart.
*"fix skills increase"*
@@mccalejk2 *sadness increase*
@@mccalejk2 Blame these laptop designers they don't exactly make it easy for us to fix even if he had gotten it to switch to the Integrated graphics it still wouldn't have been "fixed" it wouldn't be playing games anymore fr
Greg, I know this might sound little crazy or very unlikely, sometimes backlight LED can go bad. Have you tried shinning a light near the LCD pannel while it's on? I notice it does shuts off when you press the power button, like going to shutdown or sleep mode. Also I've red some of the comments saying, "try using a m.2 to PCI-E adapter with desktop GPU, which is a good idea to diagnose if the CPU/APU still works but not the DGPU! Also I have you tried using the "FN+Screen" button to switch default screen, like if you want to have extended, duplicate or just show second screen (I know you can't see thes screen but it's worth a shot) Anyways I like this series of troubleshooting Computers from viewers near you, Keep up and good luck bud!
the "FN+Screen" is a good pointer too. alot of laptops won't display on external is not told to
Fix or Flop is a great series, i am learning a lot from this series because of the wide range of configurations that come to you. This laptop one is very interesting.
Another top quailty video🥳 love this series, hope you have a nice weekend Greg 🙂
Thanks for watching!
I would have started with hooking it up to the LAN and see if it appears on the router. That way, you'll know if it is booting up. Yes, systems can boot up with a defective GPU, depending on where the issue lies exactly. Especially laptops which use some form of hybrid graphics, like you talk about. Btw the FLIR is a great addition to the kit!
Owner here: this is something I did not think of. I appreciate the suggestion. When it arrives back to me (it is on the way) I will try my best to update you if the laptop shows up on the router's app.
@@12349goku I do wonder if you would drain all of the power (hardware reset) then power it back on? Or have you tried that?
@@12349goku It's been a while ago but I've even seen a similair issue with an HP Zbook where the M.2 SSD was defective. This would cause the system not to POST or display anything. Try removing all non-essential devices. HDD, SSD, WAN card, battery and just run it off of wall power.
I’d like to add a note: there is a display cable that runs around the bezel of the monitor of the laptop. My Asus laptop did the SAME thing. If you reconnect the cable between the monitor and the keyboard you should be fine.
That could be it. reseating the display cable almost always solves the problem if the GPU didn't die. However the GPU should still get power even if the display cable is disconnected and there was no heat coming from it on the FLIR image.
although note that should still display to a external monitor when plugged in, which this wasn't doing
As another guy pointed out - if that was the case, the machine was going to boot, detect the external screen and connect to it.
I’ve been binging this playlist/series like it’s a Netflix show 😂
I use to own a computer store and work on these things all day. Sager, Asus ROG (my favorite), Alienware, MSI, even HP gaming laptops. Usually the culprit was cold or cracked bga joints under the chip, where it got hot enough to slightly melt the lead free solder and cause one of the 500 little connections to lose continuity. Usually preheating the bottom for 10 minutes and reflowing the chip with kester 951 and a large enough nozzle would resolve the issue. I want to say it was 90% effective.
So the chip may not be dead, more/less disconnected.
The ones that didn't come back to life were sent out to L2 Computer in Brooklyn NY. They have a very expensive automated IR bga solder rework machine. They're usually pretty cost effective as well.
If the laptop hasn't been sent to anyone else give them a try.
Great playlist! I'm new to building PCs (since 2019) but love to constantly learn more about troubleshooting and stuff that I hopefully won't run into in the future. Looking forward to more of this playlist!
Had a similar issue, tried a hail Mary and tightened the hell out of the heat sink screws and it worked, worth a shot.
Great content!
I have been a laptop user since 2008/2009 so I'm really grateful to watch this. I've only done my own servicing once to my previous laptop and put simply, it was arduous, and nerve wracking.
I own a Clevo Sager P775TM1-G and I love that I can replace both the CPU and GPU if they were to fail on me. Yeah the graphics card module is expensive to replace, but it is still better than sending it in and paying way more to get it repaired when you're out of warranty.
One way to possibly fix it is to bake the motherboard at 200deg C for 10 minutes with the GPU/CPU Chips facing upwards. Do this at own risk, good ventilation is necessary as the smell is quite intense. This process allows the solder to soften enough to repair any minor cracks that may have been caused by the laptop overheating. Common problem with gaming laptops in general. Fixed 2 old laptops with graphics issues like this
Thanks Greg you just saved my afternoon
Glad to hear it! :-D
IBM technician here! Your laptop skills are suprisingly good. If there is a discrete GPU it will probably be broken every time, no matter if its via slot or soldered into the board. This model would need a new planar. This model ive only swapped hinges to so its not a terrible one. Not that many businesses get gaming laptops, but some people pay for the best warranty that sends me to their house. :x
My 2010 Toshiba lappy died when I loaned it to someone who had a habit of putting it on bedding and blocking the airflow. Definitely a reball scenario. Back then I could have sent it to NYC for $125 and they said would include an updated graphics chip. I didn't do it. I looked into the DIY reballing a la XBOX 360 but never did it. I'm doing the oven thing right now, I'll keep yall posted.
@Greg Salazar I have really enjoyed the Fix or Flop videos. Carey Holzman has been recommending your cleaning videos as well. Good job!
I have the same laptop, but usually when mine doesn't boot, i can press the Novo button and it brings up options for BIOS Update, Setup, Normal Boot and stuff like that. It's a pin hole button near the right side power LED, kinda like a reset button. In Setup, there's an option to disable the discrete GPU, if that worked then definitely a problem with the GPU lol @Greg Salazar
Owner here: the button did not work unfortunately. It would not display on an external or internal. Geeksquad actually tried this for me.
@@12349goku oh wow even the reset button doesn't help! I feel like The Legion is kinda ruining your life right now, idk. :\
@@12349goku USB-C uses the iGPU so you could try using a USB-C dongle with an HDMI port. That right there would answer a lot of questions.
@@12349goku Was vantage allowed to flash the bios?
@@user-px9ez2hs7o I thought Greg tried the Thunderbolt and USB C ports for video out, without success.
You may have done this off camera, but I didn't hear you mention it. I was surprised you didn't try to boot it up with no SSD, HD, or Wifi card installed. I've seen so many times a simple short of some type on one of the removable components that causes there to be no video out. Not a good sign with the GPU showing no heat though. I think you nailed it.
My dream is always building a compact desktop rig that I could bring everywhere (because I'm a nomad stage operator that'd control broadcast and dmx system). DIY Perks has done this.
@Greg Salazar you should try using the NVME slot it can act as a PCIE and can provide display out with a riser cable.
In Norway we have an extended warranty other than just the manufacturing one. "PCs, computer components and expensive printers are expected to have a service life significantly longer than 2 years and will therefore have a complaint period of 5 years, cf. Consumer Purchase Act §27. Some parts in these products such as batteries and adapters are considered to be wear parts and will therefore not have a life expectancy of significantly longer than 2 years, these parts will therefore have a limited warranty period of 2 years." This is from the electronics store Power.
We have the same laptop in your pfp lmao
Had the exact same issue. It was the Dram slot. Had to move my single stick into slot b and bam picture came back. It guy I used removed all ram and booted without ram, screen lit up immediately but obviously wouldn’t boot without ram. But this is how he proved it was the ram slot that was the issue.
Although might not be easy, you could try blind running into the bios by using a reference Legion bios as a guide to figure the navigation/key presses to switch to IGPU. Saving and exiting will bypass the DGPU I guess? I'm not sure..but would've been worth some tries if its only a GPU issue.
I’ve been binge watching vids on pcs because I’m getting one soon for my birthday and Christmas so I’m addicted to watching random vids on them lol
What are the chances that an m.2 to pcie adaptor whit a desktop gpu and an external psu would work in this particular case?
I was just about to comment this, i love the idea, but that would also mean he couldn't use it for mobil technically!
@@VentusHarpus12 i was more thinking in the way that IF it would work, he than could activate the integrated gpu (the one in the APU/CPU) and see if it works
@@RobertCenc owner here: this is a fantastic idea! I will be exploring this option in the near future. Thank you for the suggestion!
If you got a older/weaker GPU that didn't need external power like an rx550 you wouldn't have to deal with the external PSU.
@@Spectre-wd9dl the adaptor requires power too
Send it to Luis in NYC. That guy is really good at diagnosing dead boards. From what I see it looks like the GPU is not getting solid contact to produce the image. I came across a dead Y740 with same problem after the RMA it was a bad GPU luckily the guy who bring it to me had warranty still. Get that external GPU my dude, it helped me figure out issues on many things.
No disrespect Greg, that is not how you troubleshoot and fix laptops with hardware failure.
What do you think he should have done? I havent watched the video yet but Im curious what input you might have
how would you have done it?
another thing that can be done to verify that the pc is working with no display out is trying to connect it to the network, checking the IP which was assigned to the machine from the router and then using another pc or phone to try and take an RDP session (for rdp to work a password needs to be set for the account) if this works then you know for a fact that windows is loading and there is no issue there, then we can check all devices etc and maybe get more information.
18:18 Back in 2000, after buying a 20Gb HDD from a local pc repair shop, they wanted to charge me about 75USD to hook it up which involved unplugging the molex and IDE cable from my dead HDD and just plugging them to the new one. Also wanted to charge me an extra 50USD to reinstall the OS (Windows 98). It's a good thing I learned to tinker with computers prior to (and maybe bricked a few) because these place can/will extort people for more money. That's why I don't mind fixing or upgrading a friend's pc or laptop.
Man I was hoping you could get it fixed but you did everything you could. By the end of the video I was hearing the jingle that plays when someone loses a game in the Price is Right. Dun dun dundun wuhhh🎵
I found this series and I love it. Awesome of you to do it for free even though you are already making TH-cam money. Also awesome of you to occasionally toss in an upgrade for free here or there. Keep up the great content
Lol, fixing my MSI because greedy them forgot to ad the 2nd m.2 slot components. Just fixed the order I have with Digi-Key since 1 part was on backorder til Feb 2022, and I don't want to wait that long!
I think he should put in the old ram.. mine is the y740 17in but with the 8750h and the 2080 Max-Q and mine runs flawless. Don't know if the ram speed matters but the CPU is set for 2666hz and that kit is 3200hz. Even though you can't overclock in the BIOS, I think it's worth a shot.
The gentleman at northridge fix is a beast
Oftentimes, I've found that a dead hard drive or an SSD reporting weird numbers on its SMART can prevent a boot. In my opinion, you should have checked to see if it would boot without those devices connected, as they are high failure rate components.
I think that the dgpu is working fine. In my case, the dgpu stays at 0% untill a game or a program requires it to work. So, there is no power input in the dgpu, hence no heat.
All laptops (excluding MacBooks) are smart enough to use either the igpu or the dgpu based on the workload.
The the most probable issue here should be a capacitor, resistor, IC or a fuse.
MacBooks actually has this feature... like the Early 2011 17-inch MacBook Pros had 6000M graphics (I believe it is the 6750M, correct me if I am wrong) which were prone to crippling graphics failure whereby it artifacts when something GPU intensive launches. There were workarounds such as physically disabling the dGPU by shorting two pins to make it only work on the iGPU... this iGPU with a render-only GPU has been implemented for years and it became industry standard basically when putting discrete GPU's in laptops.
Fixing laptops is the worst, especially now that they need to be thinner and smaller. Everything is shoved into a tiny ass space then you have to be columbo to know where all the little ribbon cables are and then putting them back together... I mean it is nice of them to include all those extra screws so you have them when you put it back together.. oh wait those are supposed to go somewhere 😳
Nice job on the evaluation of the laptop.
something else you can try in future that may save laptops. when i worked in a repair shop a lot of the time all we needed to do with laptops that were behaving like this was disconnect the mains and battery hold the power button in for 30 seconds reconnect all then a lot of the time it would boot again.
As an IT professional, never trust users' troubleshooting.
At the end of what Greg did, I would have got a volt meter out and look for the power rails coming up on the main board. You can also test for shorts on the power rails, which may lead to a shorted item.
Try removing the battery and powering on without it
And disconnecting the RC232 battery for a couple of minutes to reset bios
Yep, 1st thing to try.
So just a theory for the future on laptops, i think you could possibly unplug the display ribbon cable, and then attempt to power on with an external display. Maybe it would work because it would be the only display attached.
something weird with lenovo laptops i noticed working on 2 already is that clearing the CMOS (disconecting the small battery on board) will damage BIOS installation. So by clearing CMOS he might have introduced another issue.
And it worked perfectly even better
im sensing some louis rossman vibe ... keep it up greg .. fixing and flopping ... every tech guys gift and curse XD
A laptop guide, advices are pretty rare to find. Although, the component name for pc and laptop are the same, it quite different on how they are on a laptop.. I hope there's more laptop guide out there from the major pc youtuber... Great work on the vids Greg!!!
I have laptop with the same issue, it can be dead GPU or a burned mosfet or coil in GPU power supply side. You have to test the components there for short and if a lot of are shorted use the voltage injection methode starting at the Mosfet with 1.5v and 3 amps at the beginning and looking under thermal cam to find the shorted component. Mine was more complicated because two power lines were shorted together and produced a lot of heat on the CPU which I was thinking about a shorted CPU but I couldn't be because a shorted CPU doesn't heat up like this , so I found a coil which was making this issues and then in Graphic chip part there were two dead coils, by replacing those I was able to power up the laptop, it took me 6 months to diagnose it.
We need laptops to have more replaceable and upgradable components! This is totally possible. Instead of having one mainboard or motherboard, have 3 connected to each other. One for the CPU, one for the GPU, and one for the motherboard. It wouldn't even make the laptop any thicker!
we basically had or have this allready in some way. in short: to expensive. look what mxm gfx cards cost. we had replaceable cpus too but if its not a standard part, its expensive. if its standard, its not optimised for laptops. overall not worth the effort to make something what a fraction of the customers want.
That's why I use a lot of older mobile workstations and gaming laptops. Everything including the GPU and CPU are upgradeable and replaceable if something dies.
Wouldnt it be an idea to plug in a external discrete gpu like on a bench maby that way u can definitely call it on the gpu?
I find that most laptops also have a FUNCTION key combo to swap between native and external Display. take a look at the keyboard functions. and you should see display symbols with a / between them. try that while powered on and the external should turn on.
Great videos. keep them up.
There's one thing you could have done and that is to connect an external gpu to the laptop by way of the wifi connector inside the laptop, they do make adaptors for this and at least you could see a screen to run further test
Love how the email says he's ordered an ASUS TUF laptop that he can barely afford. Yeah, heres an idea, there are way cheaper laptops you can buy
Owner here: I actually returned the laptop, because I had put it on credit, and was only looking for a temporary solution. I decided to use an old notebook for about a month before building a new pc I got some deals on. So a ~1200 laptop went down to a ~$500 pc.
You are correct, I should not have been hasty in my financial decision there.
@@12349goku next time send it to somebody who knows what the hell they're doing. You need to send it to someone with a microscope and a soldering iron who knows what the hell they're doing. There's plenty of shops you can mail it to who could find and fix the issue quick and easy.
@@easley421
Yeah, any engineer could isolate the faulty component/s. I'm not convinced it's the GPU chip, I'd be using a simple multimetre to check to see if the chip is being powered at all. As this was left on all night it may be that a fault in an IC has led to it's failure or a power surge perhaps, most repairs on most electronic devices are caused by small inexpensive part failures the only problem is when that leads to other parts failing.
@@easley421 I sent it to geeksquad as stated before, and they did roughly the same as Greg, however my hopes were to have him make a video based on this about what happened to my laptop. If it was a software fix or able to boot to igpu even if the dgpu was dead, I would have been overjoyed and it would be a fantastic way to show those who go through the same. Even though it was unable to be fixed, I am not heartbroken. While I do not have any shops nearby, I will try to email some places to get a quote for reballing and component diagnostics, no replacement GPU, only smds if needed. If it doesn't work with a reball, I will unfortunately need to put it on the back burner or sell it due to lack of funds.
@@12349goku send that laptop to Northridge fix (check out their youtube channel), they'll probably figure it out.
This is why I avoid laptops except a small one I use for working/internet access when I travel. I get some people don't have the room for a desktop or students who want to also have something they can use to do work on and take to lectures but if anything goes wrong and you have no warranty left you're stuck. Gaming laptops are also stupidly expensive compared to what you could buy for that in a desktop and if anything goes wrong with a desktop you can easily replace a part within a day and at most a couple hours work if you need to replace a motherboard depending on how quick you are at removing everything and putting everything back with the new motherboard.
another great video . love this series. love the troubleshooting angle.
Just for reference Greg, Lenovo has service manuals available for their laptops which are very useful.
Great videos!
I used to work at a computer shop years ago, and people brought in laptops ALL the time like this. If it’s not as simple as replacing a broken screen, I just told them to buy a new one. Parts + labor made it not worth it for the majority, since name brands charge up the wazoo if you aren’t “authorized”.
A laptop is indeed a personal computer :D
Send it to Louis !! Like Mr Doom said it would make a great collab for you! He has all the tools and experience with laptops. You can just mail it to him and do a follow up ep via Zoom
in germany, by law, we get at least 3 years of warranty. hat has really helped me in the past (fried CPU MOBO RAM etc. ...)
One diagnostic you missed was unplugging the CMOS battery to reset the BIOS. The GPU not generating heat doesn't mean it's dead, there's no reason for it to power up during POST. Laptops like this run off the iGPU and only spin up the dGPU when software calls for it.
Perhaps some insight from a former laptop tech for major vendor that rhymes with Bell (Visit small business, residential, large companies, government offices etc etc). Loved the troubleshooting process you went through. Looks like you checked most options in a logical order. Generally how something like this would be handled (if laptop is under warranty) is in the first instance, the customer would call the support line and work with the help desk operator in troubleshooting the issue. In most cases, when the issue can not be solved over the phone the help desk would send the job out to the technician in the area. In the job, they would "shot gun" a bunch of parts that may solve the issue. In this case, more than likely they would of sent out a mainboard, display cable and display screen and provided instruction to swap over the mainboard first and see if that would solve the issue. If not, then display cable, then display screen. Its requested this way so that if the issue is resolved after replacing the mainboard, the display cable and display screen can be sent back. The faulty mainboard is also shipped back. Unsure of what process is conducted back at the vendor, but I believe the mainboards are reconditioned / repaired. Now imagine you have 8-10 jobs lined up for the day. All with similar issues. All spread over town. Time is precious and due to SLA and deadlines, spending a lot of time attempting to troubleshoot issues onsite causes headaches with customers / calls from vendor asking where you are haha. Obviously as you become more experienced, you work faster etc etc. But there is always the spanner thrown in the mix with laptop jobs. It can be cut-throat at times. Sometimes a job might be a simple battery replacement (5min job), or could be a full blown rebuild, where the laptop is in a 1000 pieces (1hr+). And this is also conducted in the clients office, home, shop etc etc. Give me a desktop PC to work on any day! Long winded post. But great content Greg. Enjoy your work.
Had this issue happen on my acer laptop. Had to flash the BIOS with a usb jumper which was so awesome to take my "bricked" laptop back from the dead.
I used to buy, repair, and sell Thinkpads in college, you could get basically anything unless it was a rare model like a T43p.
Usually the iGPU will be outputting to the in-built display by default, which it should be after resetting the CMOS. My guess is either the motherboard itself has a fault or the CPU has died (it's rare but can happen). I've had a desktop motherboard kill 3 different CPUs whilst troubleshooting... wasn't a good time, at least it was only 4th gen intel chips and not something newer, still a shame though.
Great video Greg. You've gotten my neurons firing about the solution for this. There is a new company, Framework, that makes notebooks with discrete parts that can be easily replaced like a desktop computer. Google the company's name as it's a new company.
Ravi Peiris M.D.
POWER CHOKE closest to center of motherboard also put thermal pads on those micro controlllers

Another reason for lower amount of warranty time for laptops is they account for the possibility of people traveling with them. Movement, jostling, potential to drop or spill things on it.
You're probably right, but I would have tried (at least) three more things:
* Unplug the screen from the motherboard and use the external display only
* Use different RAM, I'd expect you have some spare laptop RAM you can use for testing purposes even if you can't give it away in a repair.
* remove and replace CMOS battery to reset BIOS (I know he said he cleared the CMOS but as you said at the beginning you need to test it yourself)
4:11 For some reason, having an upside down USB A port for power really bothers me.
it was a good idea to check the Mini DIsplayPort as well as the HDMI port. They can be wired separately, with one of them still functioning off the iGPU. No such luck in this case.
Lol I checked it in the video...
@@GregSalazar Yes, I applaud the initiative.
What you can do is test resistances.
If component gets none resistance, it is propably the dead one.
Working component should give you resistance.
This could be anything. Maybe for the next time unplug the screen of the laptop itself so you know it's not grounding anything. The screens have a small logic board under the screen that goes bad all the time. I would next desolder the BIOS chip and reflashed it with the latest Lenovo BIOS. Nice video though. Fixing laptops is really hit and miss like you said.
Where i work, we repair this such issue. Its usually chipset on the board issues. Needing to be resolder. here our charges are 300myr = 70 usd at minimum. At the end of the day, i kept telling customers, if you really want to game, just get a desktop.
I was always a fan of being able to game on the move, but this is the reason I converted from a laptop to a desktop even though I always bought laptops that had interchangeable gpus and cpus.
Usually if there's an iGPU and a dGPU in a laptop, the dGPU is only used when 3D games and applications are used, the iGPU is used for BIOS/POST, BOOT time, and Desktop/2D
Even with a dead dGPU, it should still give a display from the iGPU (how do I know? had a laptop where the dGPU died, I could still use it, just not for games, web browsing was fine)
If hybrid mode is disabled on the Lenovo Legion it runs through the GPU only.
Might not be a fail dgpu. It could be a stuck value in NVRAM specially if MS Hybrid has been disabled. Simply remove the Battery, CMOS Battery and AC then press and hold the power button for 30 seconds. Then hopefully it will reset the NVRAM variables.
MSI Laptops had the same issue with a MUX switch which required a BIOS/EC hard reset.
You could even do it without taking the case off as well some laptops have a little pin hole button to which you just disconnect the PSU and hold in the pinhole button for 30 seconds.
On MSI laptops with the MUX issue the dgpu didn't power on at all as well.
Do you have an eGPU to try and see if that would work?
One possible thing to try and get a sinal out of it is a USB 3 docking station. Those come with their own gpu and dont have to rely on the internal gpu.
Oh, for the first time this early, and welcome to the laptops on the series xD
I had an Lenovo legion y520 : I updated the bios and after successfull install the laptop bootlooped 😅(1120€!)
I turned it off (the screen says do not turn off or something like that)and powered it back on…it works😂😂😂
Keep up the good work dude👍
wait what? i have a y520 too. it works ok now?
Just an FYI for the future, my laptop from 10 years ago has a bad battery and the computer tells you this when its booting up. It has a warning message while its booting from the bios screen, not sure what its called but the screen where you can press delete or whatever to get into the bios before it loads into windows.. so if its ever a issue with the battery it should tell you and you shouldn't have to guess..
The fact that is not making any beeps, means that it's a corrupt bios.
Common practice on cases like that is too take out absolutely everything, main battery and bios battery included and short the batterys contacts, together with pressing down the power button for more than a minute.
Then, power on the device without the ram and battery. Usually, after mounting the ram, it boots, even if it's really borked up, but if so, it will not work nonetheless, but hey, its a little win...
Are you gonna try connect external GPU via Thunderbolt ?
He did it still didn't work
You can pull all the RAM and see if you get a beep code on powerup for missing RAM. That would probably rule out CPU/power issues.
This guy is gonna be active fixing everything even if he s on 80s
Most of these laptop have a reset hole, check the user guide to locate it, that what you should try first, before anything.
For me the most common laptop problem is dead ram (I have no idea why) but I see you didn't try new ram, maybe both stick is dead, try cleaning the ram slot too
I see that GPU is not heating, but I use many gaming laptop and they're using IGPU for booting to windows then the software will consider which graphics to use depending on your activities, so that GPU chip shouldn't heat at all when booting.
Black screens are known problems with Lenovo machines. I've fixed them before by going to the recovery menu during startup. Press f11 when it's booting and the screen turns back on. Or it might be f8, I can't remember now.
15:18 don't forget to look back. i9 box also heating up
It might not be the gpu at all, it could be a short in the gpus power rail from a blown fuse or capacitor. These are pretty easy to remove and replace
I would assume it’s the CPU itself , being it’s not using the IGP to display anything . I had recently had a desktop with IGP but was also using a DGP . The CPU bricked when overclocking , causing my GPU to turn on and get power , but wasn’t doing anything but moving the fans and nothing coming from output. It seemed to post but no output on any display. Replaced the CPU through warranty and fixed my
Issue.
Maybe you could have tried an eGPU if you have one? Or that weird NVMe GPU that was hot a few months ago.
Or an NVMe to PCIe adapter with a classic GPU.
Okay, this might sound stupid, but aren't laptop default bios configuration should go with the iGPU (since you need to enable NVIDIA Optimus in the bios to use it) if so, why not try to clear the CMOS to make the bios configuration its default?
