Dont know the history of laptop, On the board there were two destroyed usb connectors that i replaced. The board is turning on to bios, i have picture but i dont see gtx1050 gpu in bios only intel internal gpu is working. So i checked gpu gtx1050 voltages and there is nothing...dead and cold...no nvvds, no fbvddq...nothing.
Resistence in ohms on gpu power rail seems fine. No short anywhere that i can find. So now i am trying to figure what comes first from schematic and i am lost and need help
So i figured that i need to have NVVDDS_PWROK to rise gpu voltages. But i am not sure what is prequest for NVVDDS_PWROK? As far as i can see i have to have +NVVDDS_VRON signal on U9701, and that signal comes from logic U9703, signals DGPU_PWROK and DGPU_EN_PWR? and when i go further first signal is AON_PWR_EN from pch?
Help please
