You can reset your BIOS in a few different ways, but they all have the same effect: They set all the BIOS settings back to their factory defaults. That means it resets any overclocks you enabled, turns off any features you’ve enabled manually, and even defaults the time and date.
Resetting the motherboard to its factory settings can solve common boot problems or undo changes you regret making. Here’s how to reset your BIOS.
Note: Although modern PCs and laptops typically have UEFI instead of a traditional BIOS, we’ll use the terms interchangeably in this article.
Reset your BIOS in the BIOS
Every BIOS is different, but each provides a command for resetting the BIOS. It may be labeled “BIOS Reset,” “Factory Defaults,” “Default BIOS,” or another similar term.
Step 1: Reboot your PC or start it up, then select the specific key for entering the BIOS (usually Delete or F2).
For more guidance on accessing the BIOS, see our guide on how to use the BIOS.
Step 2: Once in the BIOS, look for the key to reset the BIOS to defaults at the bottom or right-hand side of the screen.
Alternatively, refer to your motherboard’s manual or the manufacturer’s website for instructions on which key to press.
Step 3: Press the key to reset the BIOS. If prompted, reboot your PC. If not prompted, save settings and restart for the changes to take effect.
Reset your BIOS using the reset switch
Many modern motherboards have a BIOS reset switch/button. Locate it using the manual or manufacturer’s website, power off the PC, and press the button for a few seconds. Then turn on your PC to find the BIOS reset.
Reset your BIOS by removing the CMOS battery
The CMOS battery on the motherboard powers the BIOS settings when the system is off. You can reset the BIOS by removing this battery.
Step 1: Turn off the PC, remove the power cable/battery, open the case, and locate the CMOS battery.
Step 2: Remove the battery by pressing the retaining pin inside the holster.
Step 3: Press and hold the power button for 30 seconds to drain any remaining power.
Step 4: Replace the battery and other components, close the case, and plug in the power cable.
Step 5: Boot up the PC to find the BIOS reset.
