Gaming laptops classic disease - Shorted CPU/GPU mosfet - Msi gaming laptop repair

[fairrepair_en]

GPUs are actually way more resistant against shorted high-sides than CPUs. So there is always a way higher chance it actually survived. Recently i had a really challenging case on my bench where the the DrMOS was welded with a few board layers and it was necessary to dremel the short out of the board. After the restauration of the tracks and replacing all related DrMOS it turned out the GPU is working absolutely fine, like from factory.

Salut. Am fix un laptop ca acesta, a facut scurt de la mufa monitorului.. Sper ca specialistul care mi-l repara sa fie la fel de profesionist ca dvs! Spor la treaba!

Hello Sorin! On my laptop (Lenovo Legion Y720) the HDMI/DPort port is only driven by the Nvidia video chip, the integrated Intel can only show picture on the built in screen. Learned it when i replaced the old battery to a identical looking one and the laptop kept shutting down when HDMI was connected/game started. The problem was the BMS in the new battery it was only able to deliver 5 amps while the original did 9.

great video sorin ....a standard charge for just opening the laptop is the way to go ..then if gpu or cpu are gone you still get paid ..customers pay for your knowledge and experience ....and labour ....

"This is a nice MSO laptop", opens it and it's disgusting lol, that was a laugh out load moment for me anyway. Some people have no shame, you'd at least clean it before taking it to get fixed etc. Minging doesn't come close, I'm not surprised you put gloves on for that one.

Thank you very much dear teacher Sorin. Thank you 🙏😊🙏🙏

What caused the issue ? What model laptop is this ? Awesome video by the way. Fantastic job

Thank you sir, you have really boost my knowledge .

Thanks for another great video. Upgrading my cheapo microscope. Have been looking at the amscope microscopes. I have been meaning to ask you on your other videos. What microscope do you use?

I love the videos of gaming laptops..a follower from Libya..greetings..

great video as usual, but i have a question why they do not design power supply such that if the control chip detect over voltage situation due to shorted high side mosfet it also energize the low side mosfet to create a dead short and save the cpu ( in this case the charger will probably cut out due to very low resistance short)

[biproservices]

How are you gonna test if the GPU is still alive? It would be interesting to see the test process as well. Thanks! 😊

[Evhen_Velikiy]

If you measure voltage (mV) across coil while applying power supply to find a short you can exactly find one that is under load and a co0rresponding mosfet is dead.

Why don't you use your own test SSD? I have a sata and PCI-e one and planning to get an external USB one too. Way faster than having the customer test it or ask for the password and have problems later.
Multi phase VRM high side shorts can kill GPUs, but in my experience they are way more likely to survive than CPUs.

there is some rly sensitive ppl i also had in my life so many times little scratch which was from opening laptop and trey cry... so now i tell them its not made to be dissembled and little scratch like that sometimes happen sometimes not depend how hard is laptop to disassemble it some are just screws some are painful plastic clips which will leave tracks of opening for sure...

[dritanlondollukani]

Sorin put transparent plastic film at the screen around the screen and dont scrach the plastin. I dont know if i explend good. Just put some platic film around the display

[dimitrismaster]

I always clean the laptops.even after a mundane job like hdd to ssd.The speed will make it look like new, so the cleaning will add some wow effect on the customer.Its the "good as new" experience for them.Never I had complaints about scratches.However I'm sure someone will say that in the future.Its inevitable .
