Resetting By Entering BIOS When Booting

Let’s get down to how to reset BIOS settings. Accessing the BIOS varies with the motherboard installed on your PC. Every PC has a different key you must click when your computer boots to enter the BIOS. Below are keys of common brands you must click to enter their BIOS when your PC boots.

  • HP: Esc or F10.
  • Dell: F2 or F12.
  • Acer: F2 or Del.
  • ASUS: F2 or Del.
  • Lenovo: F1, F2, or Fn+F2.

  3. Exit: Once you have pressed the key or clicked ‘Load Setup Defaults,’ > ‘Yes’ on the confirmation window. After clicking yes, > click F10 to save the changes and exit. This will reset your BIOS settings.

Resetting BIOS Through UEFI Firmware Settings

UEFI is also a new addition to new PCs. Therefore, the way of resetting BIOS differs from PC to PC.

  1. Press Shift + Restart: The latest PCs tend to have UEFI through which you can access your BIOS. All you have to do is press ‘Shift + Restart’ (The restart button appears when you click on the Windows logo and then the power logo)
  2. Advanced Options: After entering the blue-colored window, click on ‘Troubleshoot’ > ‘Advanced Options’ tab.

  6. Click Yes: Click ‘Yes’ when the confirmation window appears.

The BIOS will reset once you have clicked ‘Yes,’ and your PC will reboot.

Resetting The BIOS By Picking Out CMOS Battery

  1. Shut Down PC: You need to shut your PC down and turn its power supply off. Once there’s no current flowing (Wait a couple of minutes), you may open the computer case.
  2. Remove the CMOS battery: Look for a CMOS battery attached to your motherboard. You will most likely find it close to the PCI/PCIe slots. However, the location of the CMOS battery may vary among motherboards > Carefully remove the CMOS battery from its place and wait for at least 5 minutes.

  3. Press the Power Button: Press the power button of the PC (At least 10 seconds) so that the remaining power may drain > Put the CMOS battery back into its place. Make sure the smaller side is facing down when placing it back.
  4. Assemble: Your BIOS will reset automatically after putting the CMOS battery back in place > You may reattach the computer case and power your PC on.

Resetting BIOS By Switching CMOS Jumper Pins

  1. Shut down PC: You need to shut your PC down and turn its power supply off. Once there’s no current flowing (Wait a couple of minutes) > you may open the computer case.
  2. Find Jumper: Look for the jumper near the CMOS battery. It will be sitting on 2 of the three pins on the motherboard.

  3. Switch Pins: Pick the jumper and switch the pins it is sitting on. For instance, if the jumper is sitting on pin 1 and pin 2, you should make it sit on pin 2 and pin 3.
  4. Press the power button: Press the power button of the PC (At least 10 seconds) so that the remaining power may drain.
  5. Set Jumper Back: You may return the jumper to the pins it was previously sitting on (Pin 1 and Pin 2).

What Affects Does BIOS Have On PC?

Resetting the BIOS won’t erase any data on your HDD or SSD. It restores original settings, enhancing component performance. Changes made to BIOS settings will be undone. Resetting is beneficial, especially for resolving issues caused by settings like overclocking, which can hinder PC performance. Additionally, it helps remove malware and viruses hidden in the BIOS.

Is Resetting BIOS On a Laptop Different Than On a Desktop PC?

Resetting the BIOS on a laptop is similar to the process on a desktop PC if done through the settings. However, methods like CMOS battery removal and jumper reset might differ slightly.

If your laptop has a removable back case allowing access to the motherboard, performing these methods is feasible. Yet, attempting to open a non-removable back case may void the warranty. If uncertain, consulting a service center is advisable.


Final Thoughts

Resetting the BIOS is relatively easy when done through the PC’s settings. However, some users might hold themselves back when it comes to having contact with the internal hardware of the PC (CMOS battery). Whatever the method is used, resetting the bios settings makes everybody nervous. 

If you are uncertain about the whole process or have difficulty dealing with the PC components, it is best not to try those ways to reset BIOS settings yourself. You can always head to a professional and seek their help. This will save you from damaging your PC and the burden of a big expense. In any case, we hope our guide on resetting BIOS settings has helped you greatly.
