How to fix ACPI_BIOS_ERROR in Windows 10

Reader Question:
“Hi Wally, good afternoon. My Samsung notebook has the error: acpi bios error. And the solution that was given to me in the tutorial is not for me to do on the pc, because the error appears andes to start the pc, I already tried to enter the boot screen to format the pc but none of the keys that normally go to the boot screen correspond. And it shows th error.” – Tiago Sil., Brazil (Translated)

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win7, XP, Vista – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: BIOS issues are rare but often simple. Problems like the ACPI_BIOS_Error can look cryptic and intimidating, but don’t worry. Following these steps should lead you to find the problem and fix it.

Problem

The user is not able to run Windows normally due to a blue screen error. The error is labeled ACPI_BIOS_Error.

Cause

This error may be caused by incorrect overclocking, a malfunctioning connected device, a weak motherboard cell, or incorrect BIOS settings.

Solution

Here are some ways to fix common problems which usually result in the ACPI_BIOS_Error.

Unplug Anything You Don’t Need

Unplug any device from you computer that you don’t need. You can do this by unplugging everything and then plugging in the bare minimum. Now start the computer and see if this helped fix the problem. If not, then please continue reading.

The CMOS Batter Needs To Be Replaced

This problem usually occurs in desktop computers. You will need to unscrew the computer’s cover and get access to the motherboard After that, locate the CMOS cell on the motherboard and carefully remove it.

You will need to replace this cell (CR2032) if it has no charge. You can tell if the cell has no charge by touching its -ive side with your tongue. If you feel a slight tinge, it still has charge. Now, you should reset your BIOS settings.

After you’re in, you need to go to the option that says “Reset to Default Settings” which is usually on the first page. Now, restart the computer. If it occurred due to incorrect BIOS settings, then it should have been fixed now.

If None of This Worked

If none of these instructions worked for you, then please try booting your computer with a Live Linux DVD/USB. Linux is a free operating system and you will not need to install it in order to run it. You can learn how to make a bootable Linux USB here:

Once you have a bootable Linux USB in your hands, you can try booting your computer with it.

If it runs then Windows should also run (you might need to reinstall it).

If it doesn’t run, then there’s something wrong with your computer. Please take it to a qualified computer repair shop to investigate the problem further.

Is Your PC Healthy?

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.

Happy Computing! :)
