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

Hi ya folks,
Attached is the BIOS from a Microsoft Surface Laptop 7 - Model 2036
As of right now i am unable to confirm whether this BIOS dump works or not.
But i will update soon. Hopefully in a day or two.

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,
recently I got an old decommissioned HP Compaq 6200 SFF PC. Unfortunately, it had a password-protected BIOS, preventing me from installing a fresh OS.
I decided to dump the flash straight away (therefore desoldered the chip and added a botched socket so I can do easy experiments).
First thing I did is to reflash the chip with the latest bios ( J01_0223.bin - https://support.hp.com/ee-en/drivers...tor-pc/5037900) . This was successful, at least the system booted, however it seems to have wiped out some machine information...
