              🛠️ 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,...

              Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
              by Wahaz
              Hello,

              I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
              So I thought it was a Bios problem.
              I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....
