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.
- Setup Defaults: You are most likely to find ‘Setup Defaults’ > The key will most likely be ‘F9’ > Press the key to ‘Setup Defaults.’
- Load Setup Defaults: If you can not find the setup default key below on the screen, you may look through the BIOS tabs for ‘Load Setup Defaults’ > In my case, it was under the ‘Restart’ tab.
- 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.
- 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)
- Advanced Options: After entering the blue-colored window, click on ‘Troubleshoot’ > ‘Advanced Options’ tab.
- UEFI Firmware Settings: After entering the ‘Advanced Options’ tab > ‘UEFI Firmware Settings.’
- Restart: Click ‘Restart’ to enter UEFI settings once the PC reboots.
- Setup Defaults: You will again have to look for the ‘Setup Defaults’ option or something similar. For instance, ASUS UEFI settings have ‘Load Optimized Defaults’ under the ‘Exit’ tab.
- Click Yes: Click ‘Yes’ when the confirmation window appears.
The BIOS will reset once you have clicked ‘Yes,’ and your PC will reboot.

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.
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.
