ACPI_BIOS_ERROR after Windows update – BIOS needed for HP Pavilion (Board ID 80B6)

[theamazingted]

Hello,

I’m looking for help locating the correct BIOS update or BIOS recovery SoftPaq for my HP Pavilion notebook. After a recent Windows update, the system is no longer bootable.

System information:

• Model: HP Pavilion Notebook

• Product Number: T6C51UA#ABA

• System Board ID: 80B6

• BIOS Version: F.45

• CPU: AMD A10 (2016 era system)

Problem:

• System freezes at the HP logo (spinning dots stop)

• Blue screen appears intermittently with ACPI_BIOS_ERROR

• Issue occurs even when booting from a Windows USB installer

Troubleshooting already performed:

• HP Diagnostics: Memory and Hard Drive tests PASS

• Secure Boot disabled / Legacy enabled

• USB boot enabled

• Windows recovery environment does not load correctly

• Win + B BIOS recovery partially runs but issue persists

• HP support site shows no software or drivers available for this product number

Based on the error and behavior, this appears to be a BIOS/ACPI firmware incompatibility or corruption. I believe I need a newer BIOS version (F.46 or later) or the correct BIOS recovery SoftPaq for System Board ID 80B6, but I can’t locate it.

If anyone (HP moderators or community experts) can point me to:

• The correct BIOS SoftPaq for board 80B6, or

• Instructions for creating a BIOS recovery USB for this model

I would greatly appreciate it. The laptop is currently unusable.

Thank you.

Hi:

That isn't the problem.

You can fix it easily by going into the BIOS and hiding the TPM security device, save the settings, restart the PC and you should be back up and running.

Updating the BIOS will not allow you to unhide the TPM security device, unfortunately.

After you are back up in Windows if you want to install the last BIOS update HP released for your notebook, below are the info and exe file links to it.

Thanks so much for your help. I'd tried to ChatGPT my way through it but wasn't coming up with a solution, but what you suggested works and fixed my laptop.
