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

hello friends - I have purchased a used Thinkpad X13 Gen 3 AMD variant and only after making the purchase I realised that the BIOS is locked. I have spent a bit of time browsing the forum and from what I understand it's possible the modify the BIOS that is currently on the machine and remove the password from that BIOS. For dumping the BIOS from the laptop I have ordered this ch341a programmer. Below is a photo of the password prompt:
I have taken the cover off the laptop and I found that "serial number" is "GM-0358MB" and "type number" is "21CN-S19U00".... -
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... -
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,... -
Hi everyone,
Thanks for your help in advance. I have an HP 800 G6 that has "Protected by HP Sure Start" on boot. It has a locked BIOS that I'm trying to remove with RCUnlocker, but even after unlocking it and reflashing, it doesn't appear to work. The password is still prompted when I attempt to enter the BIOS.
Using NeoProgrammer in Windows and a CH341a I was able to read two 16MB BIOS chips, a GD25Q127C and a GD25Q128x like this thread here: https://www.badcaps.net/forum/troubl...-desktop-mothe...
