Dell G15 5510 troubleshoot non-working dGPU or disabling it

[openminded]

hi,

I have a Dell G15 5510 with an intel 10th gen 8 core and I believe a RTX 3060.
I bought it as is and it seems to have had some liquid spill.

Currently the dGPU is not shown in the BIOS and does not seem to work at all ( not in dev manager either ).
Besides that, some keys on the keyboard don´t work, but it seems everything else is ok - works from power, battery, charges. etc.

I found the schematic here : https://www.badcaps.net/forum/troubl...s-and-brd-file
but cannot find the board file anywhere, except on a paid site in some black and white form.

I would like to troubleshoot the issue with the dGPU and if it is not fixible, electrically disable it ( page 26 of schematic it says : GC OFF 1.0 GPU Power ON/OFF).

Can anyone help me get started ? I have been measuring near some coils that I think power the GPU and I measures 1.0V. I basically understand too little of the whole process to work constructively.
Thank you for any hints and help!

I found some shorts near PVC183 on the board. I soldered off the caps near but the short is still present.
I found some additional information on page 37 of the schematics, a few mentions of DVT1 modify GPU sequence .
Not sure if that is related to powering the dGPU off ?
Does anyone know how to proceed? Any help is greatly appreciated!
