Hp notebook 15ac-18TU Bios installation

Ibrokemypcagain · ‎05-26-2025

I own a HP notebook 15ac-184TU, and whenever I try to boot it a Blue screen appears, Error code ACPI_BIOS_ERROR

I've tried visiting HP website for bios update files but it doesn't work, website doesn't have any files for my laptop

Plz help me 😭🙏🏻

This is the latest BIOS update HP has for your notebook (F.29):

If you can't get into Windows, use another PC and make a BIOS USB recovery flash drive so you can update the BIOS outside of Windows.

Watch these two videos:

Hi, Thanku you for the file!

I created the flash drive but the win+b combination provided in the video does not work in my laptop which is a HP notebook 15ac-184tu

So the bios update interface is not opening

Plz help

You're very welcome.

Unfortunately, that is the only way to recover the BIOS

Before I replied to your question, I downloaded the file to make sure it would create a USB recovery drive.

So if you were able to create the recovery flash drive and it didn't work, you will have to either replace the motherboard or buy a new notebook.

I can give you a few older revisions.

However, I believe that it is a lost cause.
