How To Reset Your BIOS: A Step-By-Step Guide

Resetting your BIOS can resolve a variety of issues, such as undoing unwanted changes or fixing boot problems. Whether you need to reset your BIOS to factory defaults or clear specific settings like EXPO and XMP profiles, the process is straightforward. In this guide, we’ll cover three common methods for resetting your BIOS, including using the BIOS reset function, the BIOS reset switch, and removing the CMOS battery.

Reset Your BIOS in the BIOS Settings

One of the simplest ways to reset your BIOS is by using the built-in option in the BIOS settings. Different systems have slightly different commands for resetting the BIOS, such as “Factory Defaults” or “Default BIOS.” Regardless of the term, the process for resetting BIOS settings remains similar.

1. Reboot your PC and press the appropriate key (usually Delete or F2) to access the BIOS settings. If you’re unsure which key to press, consult your motherboard manual or the system manufacturer’s website for guidance.
2. Once inside the BIOS, navigate to the section where you can reset to default settings. The option may be labeled as BIOS Reset or Factory Defaults.
3. After selecting the reset option, reboot your PC. If prompted, save any changes. Your BIOS settings should now be reset to the factory defaults.

Reset Your BIOS Using the Reset Switch

Many modern motherboards come with a dedicated BIOS reset switch, making it easier to reset the BIOS without entering the BIOS settings. This button is often located on the I/O panel or directly on the motherboard.

1. Turn off your PC and locate the BIOS reset switch. Check the motherboard manual or visit the manufacturer’s website if you’re unsure where the button is located.
2. Once found, press and hold the BIOS reset button for a few seconds (usually 5-10 seconds). The specific time may vary, so refer to the motherboard manual for accurate instructions.
3. Power your PC back on, and the BIOS should be reset to its default settings.

Reset Your BIOS by Removing the CMOS Battery

Another way to reset your BIOS is by physically removing the CMOS battery from the motherboard.

This small battery powers the BIOS when the system is off, and removing it effectively clears any saved settings.

1. Turn off your PC or laptop, unplug it, and remove any connected power source. Open the case to access the motherboard.
2. Locate the CMOS battery on your motherboard. It’s typically a small, round battery, often situated near the center of the motherboard. If it’s hard to find, consult your motherboard manual for assistance.
3. Remove the CMOS battery and hold the power button on your PC for 30 seconds to drain any remaining power. This ensures a full BIOS reset.
4. Replace the CMOS battery, reassemble your PC, and power it on. Your BIOS settings should now be reset.

By using these methods to reset your BIOS, you can easily resolve boot issues or undo any incorrect settings. Whether you use the built-in BIOS reset function, the BIOS reset switch, or remove the CMOS battery, these techniques can help get your system back to default factory settings.
