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... -
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... -

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...
