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,
I have a serious problem to program the Z590 chipset SRAM with a Management Engine after replacing the chipset.
The new chipset is factory new and is not containing any Management Engine. Any attempts to program it into the chipset under Windows ends with a failure (eg. Error 20: Management Engine Device not present, or something similar).
Due to the lack of the ME several ports on the board, including all M.2 ports aren't working, booting OS works only on USB. So it's now other way, as to program the chipset with a ME.
Usually on ASUS boards it worked... -
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 guys,
i've got this Laptop from ebay the bios was bricked. I bought it a few weeks ago and flashed it with
a CH341A Programmer first (Bios.bin attached) all that went good my bios worked and it booted up afterwards.
Now i used it and wanted more memory so i went from a 4 GB 1Rx16 to a 16GB 1Rx8 .
But it wont boot up with the new ram stick that i checked before in another laptop then i thought it was a good idea to flash the bios again
with the same .bin so i dissasembled the laptop and took out the mobo and flashed the bios again (same way i did it before)...
