    🛠️ 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

    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,...
