Hi guys,

If someone would be able to provide some expertise, I'd be very grateful.

BIOS Corruption - Cause
So I managed to corrupt my machine by installing linux and enrolling custom secure boot keys. I did choose to enroll the Microsoft keys as well, to prevent any potential bricking due to 3rd party drivers from HP being signed with those keys.
After doing that, and rebooting(it did boot, powerLED, fanspin etc.), the laptop did not give any video output on the LCD or video connectors. I think I was able to get in BIOS and trigger the beeper by pressing ESC....

Greetings badcaps community,

I havent done this for a long time and want to start it all again, after some evil and annyoing illness.
So I apologize in advance, if some phrases might sound a bit like gibberish or illogical to you.

Im trying my best to fully describe what I plan to achieve and hope I was choosing the right sub-forum for my new adventure.

I have a Elitebook 820 G1 and a Elitebook 840 G2 here.

These ask for a password when entering the BIOS, but boot just fine from the internal SSD.

I learned that desoldering...

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 received a HP elitebook G6 that had a The HP Endpoint Security Controller error when booted but 3 enters later you could use it in windows, i thought maybe a bios update helps...... i used the HP tool (it did not want to update from device manager,,, someting i did not even knew worked) after the update it bricked the laptop.

i get 7 blinks on the capslock and thats it. i desoldered the chips front and back. and made a dump. i tried one bios posted here for the 16M and the 32Mb bios.. but it would not turn on or give an error code. so now i reflashed it back in its failed state...

Hello everyone,

I’m hoping someone can help me locate a verified original BIOS dump for my Acer laptop.

This is NOT a BIOS password removal request.

I’m looking for an original 32MB SPI BIOS dump to use as a reference in case my BIOS firmware is corrupted. My plan is to first dump and back up my own BIOS as soon as my programmer arrives. I am not planning to blindly flash someone else’s BIOS.
