Diagnosing/disabling discrete GPU[edit | edit source]
Disabling discrete GPU
Tie to ground pin 4 of U2001; can short R2017 pads.
This will keep GPU in reset mode; PLTRST_VGA# remains always active (0V). Nvidia graphics is no longer visible in Device Manager. The chip (U2001) could be removed too.
Correct solution implies GPU replacement.
Remove VRAMs and GPU if like too. You can also save all 10uF/25V capacitors (0805 size), 6 in total. All these components (apart of GPU), can be reused in other repairs.
