Sorin u have helped me a lot even though I fix dead laptops and it doesn't charge I'm proud myself and I wanna say Thank u so much...May Allah bless u..
23:33 Sorin, if the motherboard can post with integrated graphics, then don't complicate this case. Just lift the gpu coil up (to separate mosfets and PWM IC from the rail) and inject 0.8V from your powersupply (during powerup laptop) and check if the dedicated graphics appears in device manager and works. Also you will have opportunity to observe the current which that gpu try to eat. btw. (info for others: if you want to inject that 0.8-1.0v from your power supply, to laptop, which is working, using original power supply, then you have to merge/connect your powersupply output ground (minus) to motherboard ground and then inject voltage to that side of the coil which is going to gpu. The coil has to be lifted up (removed), otherwise if you leave it on the board and inject voltage there, then the voltage will go to gpu and also in reverse way to mosfets and IC chip, and you don't want to do it during motherboard operation (on) (think about that coil like a bridge - you have to break that bridge when you want to inject voltage only in one direction - to gpu)
hi ive seen other with switchable graphics board neither remove the choke (inductors) or change some resistors to other solder points in the boards is that real nowdays or newer version of laptops which is better to remove chokes or is there any other ways to seclude gpu shorted ?
hi is there any other ways to remove the dedicated gpu on the laptop board on newer laptops i mean cause some others are just reposition some resistors dont know if thats on old laptop design on switchable graphics or not
Sorin, tu faci parte din vechea generație, care investighează toate posibilitățile până pune verdictul, se repară sau nu. Cei mai tineri nu fac la fel.
So the laptop is powering up: The customer can boot in Safemode - disable Nvidia GPU in device manager (it will prevent the OS to load driver and use it when iGPU is not enough for the task). Then use le laptop as a ordinary laptop for content viewving OR he can buy a Nvme to Pci-e adapter to use external graphique card ! Dell laptops bios are well made to disable peripherals, sadly it's not the case for Asus laptop but there's some exeptions (the GL552V is not one of them) Some older laptop or business laptop had their GPU connected on a seperated board, it was easier the replace.
Sorin, just to be clear... the integrated Graphics Processor from Intel and AMD CPUs moved from the chipset into the CPU itself long long time ago! So it's in the CPU itself! The last Northbrige-IGP was i think in the Core2 CPU times...
@@Palmit_ Hi, it's booting, you can see Windows loading animation @22:30 .. so you can cancel the boot or use recovery media to force the OS to launch recovery mode. From there - Troubleshoot > Advanced options > Startup Settings > Restart and then you select Safemode (F4 key) OR Troubleshoot > Advanced options > Startup Settings > Command Prompt : use this command: bcdedit /set {curren} safemode minimal (if os not corrumpted, it should boot in safemode @ the next restart) If the CPU still work correctly with the M.2 it should load the OS without problem in safemode :)
@@mryanzou hiya. good and knowledgeable advice. i do not disagree. i was foolish and i stupidly comment before seeing more video. doh! i am not sort of person to edit or delete my comments. i leave them because its me trying to hide something, or pretend be something else. i admit my mistakes but mostly learn from others. Thanks buddy :)
@@Palmit_ don't need to apology :) and you didn't said anything wrong. I was just pointing out some info on the vidéo and some more tips :) enjoy your day!
45:58 oh... I though, that you will take the shorted video-memory out, then start laptop from the original charger and inject 1.0v from your powersupply (with current limit) to that coil and then load windows and check if the dedicated gpu appears in device manager or not. This COULD give you a confirmation if is worth to fix or not. (Some of gpus can start without vmemory or partial vmemory)
4:26 if you see that the customer left CPU heatsink with two missing screws on one side, then the tension (which heatsink makes only on one side), can make crack the corner of the CPU core(die). As you know, the screws has to be open or close step by step across to keep the same level and tension on the core. So knowing this - I would start to take out the heatsink first and inspect for cracks on cpu die/core.
@@Palmit_ at 1:31 you see that missing screws not match to chassis/case. and because of that, what I said (tension) they cannot use half of the screws together with the case/chassis. (they can you all or nothing)
if it sugar, heating up will turn it brown. like caramel. add condensed milk, malt powder and baking powder stir rapidly and remove from heat. quickly place mixture on to cooling board (or silicone mould) and spread thickly but evenly. coat in drizzle of warm melted chocolate and allow to cool for Malteser(tm) energysnack while you work :) 😁
question if i were to disable a on board gpu why the coil(inductors,choke) is the only one should be remove why not the mosfet high and low? and some others ive seen just reorienting somes resistors is this something to do which switch wing?
good point. matching the memory sticks is ideal and helpful. but only noticeable on lower spec machines. so long as mem spec matches.. that's good enough on lower spec devices :)
That was a rollercoaster of emotions, and a very good vid to watch. Can you pull the RAM and check the GPU directly for shorts, or is it just going to show that same 7ohm, ie, none the wiser - lol -.
Maybe........ Turn the GPU off in the BIOS if the customer only needs basic graphics and save some money and risk? Excellent can of worms this one where you removed the heatsink and discovered its shorted GPU Ram and maybe damaged GPU too. Experience is everything in board repair as time taken and knowing when to stop and move on to next one is how you stay profitable, As a hobby, one can spend all the time to work on these things especially if its a valuable item and needs to be saved.
I do same thing!!. i am careful to avoid di-ionised water. distilled water is better in electronics. less "fuzz". also with new boards or self build kits. i wash all the factory "oils" off to make better soldering joints. :)
Sorin u have helped me a lot even though I fix dead laptops and it doesn't charge I'm proud myself and I wanna say Thank u so much...May Allah bless u..
I'm actually making money using everything I learned from Sorin. I just can't thank him enough

Thank you for your input... it helps a lot to have different approach when troubleshooting.
@@repairtech9320 you're welcome.
I edited my post and add additional information "BTW" at the end

Greetings from Morocco, our dear teacher, we learned a lot from you and we are still learning, may God bless him
Thank you Sorin we really appreciate your lessons u have millions of students around the world
Congrats on 300K subscribers, Sorin!!!
Thank you!
35:00 just lift the coil up to separate gpu from mosfets and pwm controller and check on which SIDE of the coil is the short.

true
The VRAM supply voltage is connected to the memory controller in the GPU. There is a 90% chance that the GPU has died.
Welcome back
On the power management chip you re-flowed I think there is a solder bridge at the top two pins.
i like on time, thank you Mr. Sorin..
Good one. I never needed a dedicated graphic card. Always used de onboard one. But also never used to game. The ball it is passed to the customer now.
Thank you Sorin
If you start windows in safe mode you can disable graphics in device manager
i think you need to get it to boot, first 👍 🙂

Great video as always, but please don't use the super annoying beep mode, please Sorin this is my relax time :)
Yes me too. My dog is afraid of the beep because it is the same sound as he training collar warning before he get shock. 😧

i think the missing heat sink screws are from part of outer case to chassis.
ahh. radek stopyra, you edited.
@@Palmit_ yeah I edited because when he took the heatsink out I realized thah I made mistake and it was cpu not gpu. So I corrected my post.

Usually can turn completely off dedicated GPU from BIOS.
if it sugar, heating up will turn it brown. like caramel. add condensed milk, malt powder and baking powder stir rapidly and remove from heat. quickly place mixture on to cooling board (or silicone mould) and spread thickly but evenly. coat in drizzle of warm melted chocolate and allow to cool for Malteser(tm) energysnack while you work :) 😁
Mulțumim
Anyone know what time the streams are? I searched both channels and even twitch but don’t see. I’m in NY and 4 hours behind but will make it :)
nice work (:
question if i were to disable a on board gpu why the coil(inductors,choke) is the only one should be remove why not the mosfet high and low? and some others ive seen just reorienting somes resistors is this something to do which switch wing?
What is the hot air temperature that reach's the component?
Hey
Ram Memory needs to be changed all at once! For if you change 1-2-3 then there will be errors.
Pick these and you can replace all at once
good point. matching the memory sticks is ideal and helpful. but only noticeable on lower spec machines. so long as mem spec matches.. that's good enough on lower spec devices :)
That was a rollercoaster of emotions, and a very good vid to watch.
Can you pull the RAM and check the GPU directly for shorts, or is it just going to show that same 7ohm, ie, none the wiser - lol -.
Can you check the memory controller pins on the GPU, because doesn't that short when RAM is shorted.
when I see an ROG laptop I always know it's gonna be a shorted mosfet or cap
or what i call a "dust duvet" lol. but not so in this video. but "dust duvet" loves to cling to static and incubate components! 🙂

Disable the GPU
You should charge repair attempt fee coz time is money and you spend lots of time to try to fix it, i'm just saying.
yeap as it says @radekstopyra4720 , just disable the graphics chip and work only with integrated graphics.......
