Hello. I have similar problem with one of these boards - I have one school laptop that i need to fix that have the BIOS "corrupted" - do not even boot to BIOS it self. Changing the UEFI from another (damaged) board and the system boots to UEFI but refuses "to see" (it blocks the access to) the SSD. NOTE - Can boot to USB Linux in it but the SATA SSD wont show up in kernel. Of course cannot boot to Windows because i do not have the SSD functional.
Now,t his is clearly some ME or the security module (CUCo) inside that is blocking or not enabling SATA interface. Using UEFITool we can see exactly that module in the flash file.
I am trying to detect where the serial number is stored so i can copy (or write it) to the known good boot UEFI. I have contacted the importer asking them if they can send me an original file to flash it but they refuse - they want to sell another motherboard... so is not an option. The motherboard is good...
I do not think that cleaning the ME region will resolve the issue. There are some scripts that disable ME - i am reading them and try to see if i can.
Trying also to clean NVRAM, because it can cause freezing in some laptops after the BIOS could even switch on the graphics.
Comparing the EC zone and the BIOS (code) modules between two files (dumped both bios chip) they are equal - so the problem is in the "data" segments (NVRAM) not the code (but it is buggy because of this lockup).
The UEFITool can extract all modules without any problem in any of this two dumps, so the "corruption" is not bad flashing or bad flash sector, or else there were errors.
NOTE/IMPORTANT: I do not want to disable nor remove the CUCo module because it is needed to be there - so we can block the computer if conditions apply. But i want to know how to fix this UEFI so i can repair future cases - those are school laptops and if we can save some money to the organization, better.Comment

Ok, so lets see what you can make.
Attached is the "BAD" flash with its serial number in its name (GW1W1490006778), and
one that is working ok in its respective motherboard (GW1W149001227). As i wrote before, if i solder the "OK" chip in de "BAD" motherboard, the system works aside the SATA port not "detected".
Note: I uploaded ZIP file because i can not upload bin. The "_OK" and "_BAD" part, of course, are not in the Serial Number...

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.... -
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

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,... -
Hello,
I have an EliteBook x360 G3 where I had to replace the motherboard. Everything is working fine and there are no errors during boot. However, I have the issue that the serial number in the BIOS is incorrect. When I run the DMI tool under Windows, I get an error stating that I am not in Unlocked Mode and therefore cannot make any changes. I was able to change the Asset Tag directly in the BIOS. Now I am wondering, can I simply read the BIOS chip, change the serial number with a hex editor, and write it back, or what other options do I have? The old motherboard did not work at...
