Re: bios Nitro 5 FH51M LA-J871P REV1.0.
I happened to work yesterday on this board , here is your cleaned ME and BIOS from website. Your dump does not show any DMI region, it is F'ed out. Should be from 00B2D000 to 00B2FFFF, 3000h long. Take a couple of readings again and compare all three before programming. Read chip again after programming, compare with this file.
Please report back.Leave a comment:

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 everyone.
I'm here to ask for help troubleshooting an issue with my Acer Nitro 5 An55-515. Board number fh51m LAJ871P .
The laptop turns on without any image, and after inspection, I noticed the 1.2V voltage was reading 8V spikes. The PQM1 MOSFET's gate was shorted to the source.
I replaced PQM1, PQM2, and PUM1. After turning on the machine, the 1.2V voltage appears correctly for about 1 minute, but after that, PQM1 shorted again. The MOSFET and controller assembly has already been replaced twice and continues to blow. I can't understand what's going on. I should also add... -

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,...
