    [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,...

    The right BIOS Programmer - The right software (HP Elitebook 820 G1, 840 G2) no soldering, EC, DMI, ME
    by STKR123
    Greetings badcaps community,

    I havent done this for a long time and want to start it all again, after some evil and annyoing illness.
    So I apologize in advance, if some phrases might sound a bit like gibberish or illogical to you.

    Im trying my best to fully describe what I plan to achieve and hope I was choosing the right sub-forum for my new adventure.

    I have a Elitebook 820 G1 and a Elitebook 840 G2 here.

    These ask for a password when entering the BIOS, but boot just fine from the internal SSD.

    I learned that desoldering...

    🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
    by macabook
    Hello everyone,

    I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
    🧩 Initial Issue
    • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
    • External display (HDMI) shows

    Elitebook 850 G5 BIOS bricked
    by Guest
    Hello,

    I have an EliteBook 850 G5. After a Windows update, including a BIOS update, the notebook turns on, but the screen remains black, and the fans spin at high speed—nothing else happens.

    I assume the BIOS update failed, so I searched for the BIOS chip.

    I found a Winbond chip located between the RAM and the hard drive, which has a size of 32 MB.

    However, the BIOS update available on HP's website is only 17 MB in size. I used the update version that was previously installed when the notebook was still working.

    Can the corrupted...
