    Alienware 13R3 bios mod request - to disable dedicated graphics (dgpu failure)

    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

      Alienware Aurora R15 accidentally flashed with XPS 8960 BIOS
      by drux
      Hi,
      I've had an ssd that was previously used on dell xps 8960 and then it was installed in Alienware Aurora R15(intel version). On first windows boot in R15 windows started bios update and loaded bios for xps 8960(r15 and xps8960 essentially have same motherboards).

      Now it has xps 8960 bios that looks different from alienware bios and when I'm trying to run bios update files for R15, I get unsupported platform error.

      These models have AMI/Aptio BIOS.

      Tried to edit product info with DMI Edit to change values back to Alienware R15, but it does not want...

      How do I flash bios to an Alienware M16 R1 AMD edition?
      by Arc717
      I am trying to downgrade my bios on my Alienware so I can undervolt & overclock my CPU, and overclock my ram. I need to get to bios 1.2.2 for this. Dell doesn't allow downgrades, and their bios file is an exe compiled in c++, so I can't decompile it easily. I am wondering if I can flash the bios manually using a usb flasher. I would like to know if this is possible, and if so, where the bios chip would be. I know flashers are pretty cheap and the bios chip is 8-pin. There are two of these chips only when I open the back panel of the laptop. I'm not sure if there are any on the other side of...

      ASUS TP500LA BIOS request/repair/merge?
      by jbonavita
      Hi, my laptop wont boot at all
      With original bios no POST, only LED lights
      With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
      Some issues
      A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
      B- If updated from 500LN version 203 to 300, the battery stops being recognized

      Things I tried

      1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

      [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
      by zenius
      Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

      Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...
