Resolving ACPI BIOS Error in Ubuntu: A Comprehensive Guide

What is ACPI BIOS Error in Ubuntu?

ACPI (Advanced Configuration and Power Interface) is an industry standard that defines how hardware components interact with the operating system. In Ubuntu, an ACPI BIOS error typically indicates an issue with the communication between the BIOS and the operating system, causing instability during the boot process. This error can manifest in various forms and is often accompanied by error codes or specific error messages.

How to Fix Ubuntu ACPI BIOS Error

1. Verify Hardware Compatibility
   

   Before troubleshooting the ACPI BIOS error, ensure that your hardware components are fully compatible with Ubuntu. Check the Ubuntu Hardware Compatibility List (HCL) or the manufacturer’s website for any known compatibility issues.

2. Update BIOS Firmware
   

   Outdated BIOS firmware can sometimes trigger ACPI errors. Visit your computer manufacturer’s website and search for the latest BIOS update for your specific model. Follow the manufacturer’s instructions to install the update carefully.

3. Disable ACPI
   

   If updating the BIOS firmware doesn’t resolve the issue, you can try disabling ACPI in the BIOS settings. Restart your computer and enter the BIOS setup by pressing a specific key (usually Del, F2, or F12) during the boot process. Locate the ACPI settings and disable it. Save the changes and restart your system.

4. Modify Kernel Boot Parameters
   

   Another method to tackle ACPI errors is by modifying the kernel boot parameters. During the boot process, access the GRUB menu by pressing the Shift key (or Esc on some systems). Select your Ubuntu installation and press “e” to edit the boot options. Locate the line starting with “linux” or “linuxefi” and append “acpi=off” or “acpi=force” at the end of the line. Press Ctrl+X or F10 to boot with the modified parameters.

Solutions to the ACPI BIOS Error Problem

Solution 1:

1. Open /etc/default/grub with root access using a text editor like gedit.
2. Add loglevel=3 to the line GRUB_CMDLINE_LINUX_DEFAULT=’quiet splash’.
3. Save the changes, close the file, and run sudo update-grub.
4. Reboot and check the results.

Solution 2:

1. Press the Shift key during boot to access the Grub menu.
2. Highlight the desired entry and press “e” to edit it.
3. Locate the line starting with “linux” and press the End key to move to the end of the line.
4. Add acpi=off to the end of the line.
5. Press Ctrl+X to boot.
6. To make this change permanent, edit /etc/default/grub, change GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash” to GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash acpi=off”, save and exit the file.
7. Run sudo update-grub and reboot.

Solution 3:

1. Intercept the boot menu by holding the Shift key.
2. At the end of the Kernel line, add acpi_osi=Linux.
3. Press Ctrl+X or F10 to confirm.
4. Edit /etc/default/grub file and add acpi_osi=Linux for a permanent workaround.
5. Update GRUB (sudo update-grub).
6. Reboot the system.

Solution 4:

Tip 1:

• Open the /etc/default/grub file.
• Add the line GRUB_CMDLINE_LINUX_DEFAULT=”intremap=off”.
• Save the file and update GRUB.
• Add acpi=off to the end of the line.
• Reboot and check if the error is resolved.

Tip 2:

• Access the text-only virtual console with the Ctrl+Alt+F3 keyboard combination when the boot process stops at a black screen.
• Log in to the virtual console.
• Run the following commands:
• sudo ubuntu-drivers autoinstall
• sudo reboot

Solution 5:

1. Run journalctl -x to identify the booting error code.
2. Open the /etc/default/grub file with sudo gedit /etc/default/grub.
3. Modify the line GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash” to GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash loglevel=3″.
4. Save the file and run sudo update-grub.
5. Reboot the device.

Solution 6:

1. To resolve the error, perform a firmware update:
2. Run sudo fwupdmgr get-updates && sudo fwupdmgr update.
