37:15 : the hot spot disappeared because you wiped the CPU clean, which transformed it into IR-mirror, so after that you were seeing your ceiling (room temp). some surfaces even non reflective to the naked eye (like non polished aluminium) are perfect mirrors when seen through thermal cam.

It's now become common place for machines to be bricked by BIOS and Firmware updates that particularly Windows 11 pushes down. I reflash on average 3 to 4 machines a week due to this.

Sorin, my ASUS r753u failed with bios update which came from win10. It’s not manufacturer. They outsourced it to windows since not every customer is doing bios updates over a few years. This comment is in context to older video. It’s also a way to end a working laptop after 6 years of use. They want to customers to buy every 2 years. All i do is coding and Computer Science Projects. Good enough computing power for a student.
Amazing process of identifying the root cause. That was very interesting and a lot of learning to take from. Thank you Sorin for sharing this great knowledge with us. The 2 boards rest in peace😢 until they become useful as organ donors😊.
Sometimes it's the journey and not the (faulty) destination that's important :) You can't fix them all, but it's great to see you trying so we can learn more fault-finding skills.
My lenovo legion 5 died after a year and a half. I used to be a big lenovo fan but not now. Unacceptable. Surfed the net and I find I am not alone. Look up issues for lenovo buyers beware. Also see what they are saying about customer service. Watching this video and others has helped me realize what problem my machine is having. Thanks for the informative videos.
What do you mean by "died"? My Legion 5 is one year old now and the only issue I had was that my SSD died which the warranty covered, warranty is 2 years, yours should be covered too unless you opened it or misused it.

Then it finally seemed to struggle when I went to copy files to a usb and would just shut down. Then it would not start. Only the keyboard is lit and the screen is black.

@@jimheston9127 Sounds like a battery related issue which is strange because I've been using mine plugged in since the first day I bought it for at least 4 hours a day every day, never experienced any battery related issues and I can still run it unplugged for that time, I mean it depends, maybe yours was factory faulty, there can be lots of issues, maybe you've been using a higher source of power than recommended, who knows.
@@kenshi7563 it was all good in the beginning and was able to use it in airports on a few trips on battery. I have only used that brick of a power supply that came with the computer. I imagine I got a lemon.
I've owned a couple of laptops that constantly killed the GPU , after replacing several GPU boards, I found out that, SOMEHOW, the board had VRAM thermal cooling pads that were too thick, ordinarily this may not have caused me to be alarmed until I realized one thing...Thermal pads that are too thick caused the heatsink plate to lift up off of the CPU/GPU(since they require thermal paste), causing an overheating issue that totally destroyed the CPU/GPU.
I too have a lenovo legion 5 with what appears to be a shorted gpu if I lift up one side of the coils the voltage come up and is correct so clearly the gpu and or the vram are rooted I plan on replacing the gpu die for the fun of it but I do t have high hopes
I have a Lenovo Legion 5 gen 5 (I think - has the Ryzen 7 4800H). It's a beautiful laptop, great keyboard, works well with Linux. Upgradability is also awesome! I want to change the screen from a 144Hz panel to a 120Hz panel (because the 144Hz panel doesn't have a 60Hz option, something that is useful for me).
for who said that windows update doesn't deliver BIOS updates. i can confirm that i have delt with this issue on asus brand, but as far as i know, all manufacturers delivered bios updates specially when the intel gen 7 and under cpus had that 0-day exploit regarding xmp overclock. so yeah, you can get bios updates with a simple automatic windows update. 100%. :)
stopped the video at 05:18.... wow that is one seriously welded mosfet. I wonder if you end up having to remove the one below it as well to rebuild the traces
I would like to know if theirs any type of motherboard reader for phone so I could recover all data including pictures everything and send to new phone from the old phone one of the IC chips broke off from the motherboard and now the phone will not turn on or charge power ... this happened because I was replacing a screen to the phone but one of the screws were difficult to remove when I finally did then is were I noticed a chip had broken off. Can anyone help ? Or know how to transfer data ? The problem is I can't turn the old phone on so want to know is there another way or is it completely lost ??
@@blaze-jb4xz If you're breaking chips off a phone, you need to take it to someone who's got better skills and might be able to replace the chip. As long as you haven't damaged the board.

20:35 - I would turn it off before the CPU over heats, triggering my anxiety now. Was waiting for the magic smoke from the CPU. (Yes, I know they have thermal shutdown buuuuut, turn it off.)

Yes a nice looking laptop 💻 Sounds like a duck 🦆 but it’s a 💀 dead cpu . And why again? A waste of time. Gaming laptops are bad 15amps 300watt you can kil my wife with it or a 🦆
300w is fine for the hardware they are using . This year there even are some laptops with 330w power supplies . Anyway, for Lenovo they simply said fk it and used the 300w supply for all their laptops instead of only the top specs ones that actually use 200 something w combined . Thats fine tho, everyone says that you dont want your power supply to need to work at 100% of its capacity
You can only buy these CPUs second hand, desoldered from another motherboard. You pay a lot of money, do a lot of work and you can't even be sure the replacement CPU works when you buy it. That's why almost no one replaces them.
@@fabian11235 That's right, and who's going to want to pay him after he does all the work and it still doesn't work because the spare is faulty? And then he has to open a dispute with Ebay, etc. Definitely not worth it unless you have a known good supplier...or the customer supplies the spare, just maybe.
Sorin: HELLO, so we are back, so this time we have a NICE LAPTOP 😅😅😅😅
😅😅😅😅
Lol.....he must be used to seeing crap laptops like mine ;-)
Tell you what, though, even though mine is 12-yr old crap....i CAN change the CPU. So much for progress, eh?

Thanks for sharing! Will there be a point when you try a Ryzen CPU replacement :) ?

you can use CRU to have custom refresh rate mine have only 165 but i set it to 90 and 60 when using battery
@@ucdungn2859 Nice - thanks for the tip. I think I've heard of CRU before - it's a Windows-only application. I'm using Linux.

What about reballing? have you tried to reball GPU or CPU?
Easy fix, new Motherboard...
10 ohm on vrm rail is not a short is it? Isn't it normal with even lower resistance on these 1v and 1.2v rails?

Can it be s short on the board itself under the CPU and not CPU itself ?
