Thank you. I compare it to the one I edited using HxD, and it says its the same, so I guess we edit the same thing on the file. However, already did try this and it's still asking for bios password.
Also, should I boot the laptop to bios first ? or its just fine to boot it normally, because in my case it boot normally first, and when I boot to bios its still asking for Password, and try to read the bin file again, and the hex/code revert back to stock.Comment

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.

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.... -
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
