How Does Resetting BIOS Settings Affect The PC?

Resetting the BIOS will not wipe any saved data on your HDD or SSD. The reset will restore the settings to how they were originally set so that the components can deliver their designated tasks efficiently. Any alterations that you made before in the BIOS settings will be undone.

Moreover, resetting the BIOS also helps the PC at times. Occasionally, some settings, like overclocking, make it difficult for your PC to run as it should. A BIOS reset fixes this problem. Moreover, malware and viruses often hide in the BIOS. A reset can also help wipe them off your PC.

Is Resetting BIOS On Laptop Different Than On Desktop PC?

Resetting BIOS on a laptop is similar as long as it is done through the settings. The process is the same as it is on the desktop PC. However, the CMOS battery removal and jumper reset might differ slightly from the desktop PC. If your laptop has a removable back case and you can access the motherboard, performing the CMOS battery removal and jumper reset method is okay.

However, if the back case of your laptop is not removable and you still try to open it, it may void the laptop’s warranty. If you are unsure whether the laptop’s back case is removable, you can head to a service center that may help you with your problem.

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).

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 that our guide on how to reset BIOS settings has helped you greatly.
