Hi everyone, hope to get someone to help and modify bios rom for me.
I need to disable dedicated nvidia graphics chip permanently.
GPU chip had failed(cracked silicon DIE) and I can only use laptop without failing if I disable nvidia graphics in dev manager (but it still draws power from battery and generates thermal signature.
Ideally if it was disabled from bios at preboot.
I believe it is possible, because if I attatch external alienware graphics amplifier , laptop at boot will disable dedicated graphics #1 (failed one) and will only boot with AGA option dedicatedgraphics#2 , but I am able to disconnect AGA while using laptop and then the ideal scenario happens - device manager no longer show any dedicated graphics, only intel HD 630 graphics, which is ideal for this fix.
I am aware that I loose sleep/standby/hibernate features while booted with AGA, so thats not a problem. (Unless its possible to manipulate bios ROM in such way that all hidden/advanced options are shown and enabled, Im willing to experiment)
I am currently on 1.2.4 bios version. I can Downgrade or Upgrade to any other version if necessary. Also have bios flashing tools/hardware and if necessary can flash bios directly to the chip if modifications can be done to the BIOS rom.
Hope someone can help me.
Thanks
