Hello,
I'm currently dealing with a BIOS corruption issue on my HP ProDesk 600 G1 SFF desktop PC.
After the BIOS got corrupted, my PC was showing no display, and I had to take it to a repair shop where the technician removed the BIOS chip from the motherboard and installed a BIOS I provided from a file I downloaded from the official HP website.
While the display issue was fixed and the system is powering up again, there's one major problem: the Ethernet MAC address is now showing as FF:FF:FF:FF:FF:FF, indicating that it's been wiped or corrupted as well.... -
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,
as noobie to this please excuse my lack of experience.
I am trying to remove a BIOS password from this machine:
HP ProDesk 400 G6 Mini
but so far I still have no success.
I bought CH341 programmer and decided to give it a try.
The programmer came with 8 pin cables and connectors or whatever everything else is called so I had to buy a new 16 pin cable because the chip which I think is the BIOS is with 16 pins..
I connected everything and downloaded AsProgrammer and NeoProgrammer then installed drivers... -
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...
