@jbreuer, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding ACPI BIOS Error Troubleshooting!

• Once inside the BIOS Setup, use the arrow keys to navigate to the Exit menu.
• Select "Load Setup Defaults" or "Restore Defaults" (the specific wording might vary by BIOS version).
• Confirm the selection and save the changes.

Update BIOS:

• Check if there is a newer BIOS version available for your notebook on the HP Support website.
• Download the update and follow the instructions provided to install the new BIOS firmware.

Check Storage and Memory Components:

• Turn off the notebook and disconnect all external devices.
• Remove and then reseat the hard drive and memory modules to ensure that they are properly connected.

Clear the CMOS:

@jbreuer, let me know how it goes!

Dear ZOEY7886,

I entered the BIOS Setup pressing the F10 key while booting the laptop.

In the "exit menu" I selected "Load Setup defaults", saved the change and rebooted again

The error still comes up.

In the BIOS Setup I do not see any item refering to the setup of ACPI. This is may be because I am not able to enter the advanced settings in the BIOS setup.

Can you please advise me how I can proceed to fix the problem? Thank you.

Regards

Hi @jbreuer, 

Thanks for the update, and I’m really sorry to hear the issue is still persisting — that blue screen with the ACPI BIOS error can definitely feel frustrating when you're just trying to get back to work. You're doing all the right things so far!

Since the default BIOS reset didn’t help and you can’t access advanced ACPI settings (which are often locked in consumer models), here are a couple of steps you can try next:

BIOS Update (Strongly Recommended):

Sometimes, a BIOS update resolves ACPI compatibility issues — especially after a Windows upgrade.
➡️ On another device, head over to the HP Drivers Page
Search using your product number: L2S55EA
Download the latest BIOS update (if available), and follow the instructions for creating a bootable USB to install it.

System Recovery or Reinstallation

If the BIOS is up to date but you're still hitting the error, the issue may be tied to Windows or a driver.
Try booting into HP Recovery Environment using F11 at startup (if accessible), or reinstall Windows via a bootable USB.

Hope this helps! 

Take care, and have an amazing day!

Because nothing helps me to get my laptop working, I decided to buy a new one.

Go into the BIOS and change the TPM setting to Disabled/Hidden.
