                      🛠️ 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 Zenbook Pro Duo UX8402ZA BIOS
                      by pirati
                      Hello everyone,

                      I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.

                      When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.

                      I decided to try flashing a new BIOS, but since I didn’t want to desolder...

                      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,...
