If you're seeing a bitlocker window. BIOS, or more accurately UEFI is 'probably' fine. A corrrupt UEFI usually bricks the entire board. But does still sound like it could be a mobo issue. Would normally check for disconnected ribbon cables or damage. But honestly, if it's still in warranty. Just RMA it. Any kind of prodding of the UEFI from outside the UEFI settings is practically guaranteed to be outside of your capabilities, entirely because you just don't have the equipment, software, diagrams or whatever needed to do that.

r/sysadmin on Reddit: When all else fails what is the final fix for a corrupted bios?
September 30, 2023 -
I'm just curious, Is it physically flashing the bios chip with a socket of some sort?.
I've got a Dell laptop that is completely jacked up. The laptop is still under warranty, but I'm just curious if a motherboard replacement is what it needs.
Keyboard will not work, nor will the trackpad. I can sometimes boot to bios but cannot do anything because the keyboard doesent work. The only key that works in the bios is the windows lock button, and that cycles left through the menu, but i cannot escape, or select anything. I cannot Input the bitlocker code (keyboard wont work) no usb keyboard will work. I'm assuming no USB drivers are being loaded. I unplugged the battery to try and reset the bios.
The only key that works is the windows lock button, and that inputs a 4 into bitlocker. No other keys work.

Most major manufacturers have a hard-coded bios recovery sequence, whereby you place a specifically named bios image on a (usually) fat32-formatted flash drive, hold down 1 or more specific keys at power-on, and if the expected file is found, it'll be flashed to the chip. You'd need to google your particular line of laptop, download the latest bios version, and try and find the doc, if it was written up, or an internal techdoc was spidered. Alternatively, you can get a usb-attached eeprom programmer, and a set of 'whiskers'? Pull apart the machine, extremely carefully place the leads on the rigs (exposed) pins for the bios chip, and write a fresh image that way. Both doable, both non-trivial, if it's your first time/you don't need to do this repeatedly. As others have said, if it's under warranty, just kick it back to the manufacturer.

It wouldn't be possible for the BIOS to become corrupt unless you were actively performing a BIOS update or have physically damaged/touched the BIOS chip. Was it possibly just that your BIOS Settings/Memory was corrupted, which could be the result of a dead CMOS battery having lost the memory? Can you share the full message displayed? If BIOS is not able to start, attempting recovery on your Windows installation will have no effect (as you are seeking from HP). Your personal files and Windows Installation, are presumably perfectly fine, its the motherboard (specifically the BIOS) that is broken, and may require consultation/repair from HP if the BIOS is truly corrupt. (If BIOS is corrupt, you have no ability to recover the system, BIOS needs to be functional to flash BIOS. Repair will require specialized tools by HP to re-flash the chip from scratch).
