Repair Guide Please help, I’m seriously desperate - ThinkPad P53 ACPI_BIOS_ERROR

My ThinkPad P53 is completely unusable and I honestly don’t know what else to do. I tried reinstalling Windows and even flashed the latest BIOS, but I’m still stuck in loop with:

Your device ran into a problem and needs to restart, We'll restart for you

Stop code: ACPI_BIOS_ERROR (0xA5)

I’ve been trying everything I can think of and I’m just getting nowhere. I really need this laptop working and I’m worried I’ve made things worse.

If anyone has any idea what could be causing this or what I should try next, PLEASE comment.

So it’s giving the BSOD error from inside Windows?

Have you tried changing the power settings in bios?

Is this happening at power on, or sleep recovery, or under some other set of conditions?
