Greetings,
I have an Acer Nitro that suddenly turned off while I was using it. No lights, no power, stock DC power supply goes into safe mode when plugged, battery connector is also seem to be shorted while the battery is connected. No visible faulty components are on the board.
Narrowing down the issue I found shorted dGPU 1V_VGACORE rail to be a suspect.
Removing PU8510 (and PU8511) seems to eliminate the issue, the laptop is working on iGPU, charging (new battery) is also fine.
Replacing PU8510 or PU8511 did not seem to solve the issue, the same symptoms come back again so I would need some guidance what to check further (PU8609 driver IC?) hoping the dGPU can be still revived. Or perhaps not...
Any comments are welcome!
