this is a moment to salute the laptop from the previous video that had a separate GPU board!!!

[@kepler104]

Going for a 20 min walk, Sorin uploads a 20 min video, perfect

[@retrocomputinggrotto]

Its a real shame manufacturers stopped putting GPUs on a removable board. They'd much rather you purchase a whole new laptop I guess.

[@stefan7231]

You should really get into VRAM diagnosing, reballing and replacent :D

[@Timpano_Francesco_Repairs]

Hi Sorin, good job you save the laptop....is not a coplete fix , but OEM wont you can't be able to repair don't worry.... but customer can still use the laptop and this your win... bye Francesco Timpano from florence Italy and thank for the mouse curson modification, noe is a pleasure follow you🤗🤗

Alex from Northridgefix usually changes these VRAM shorted mosfets to fix, once he explained why the GPU or chipset don't burn. These mosfets usually acts in fact like DRmos that works monitoring voltage and current and protects the memory or any other component after it. This is why the ohms impedance are similar to a GPU or CPU burned

Excellent work, Very educational video, Thanks!

[@giulianoyula]

Thanks, learning a lot , congrats from argentina

[@davutozturk3348]

Thanks good job.

[@darcyke]

Great Job thank you

[@rfr653]

Good job mate 👍

[@soumyaranjanmoharana4804]

Can you try replacing the removed mosfet? Maybe the yellow triangle is due to absence of adequate power for ram?

[@pihmusik]

Dobra robota kolego!!!!

[@shai1985]

Hi Sorin, great work! But im not confident the VRAM is dead. I think right approach is to replace the mosfet and check.

Interesting comparison cause you cannot find a brand new unused kidney either 😅 All you can find are taken out from donor bodies. But yeah, probably finding a good kidney is easier than finding a working, good Nvidia chip 🙃

[@chumatez]

Nice one

[@mihaioleniuc1642]

Nice! 😎

Hi, Sorin what is youre method for remove black epoxy glue that is under the lenovo apu ?

[@lucataszarek8782]

Hello🤝good job 👍👍👍👍👍👏👏👏👏👏👋👋👋👋👋👋👋

If you buy an used GPU + VRAMS you are gonna expend over $350, for $500 you can buy a working motherboard tested, so there is no point on replacing the chips with the work it will take if for only $150 more you can get a full working motherboard. A few months ago I bought the motherboard for my Nitro 5 that had a dead CPU and is working perfectly again, I also upgraded from an i5 to an i7 because it was only $30 more.
