How to Reset PC BIOS/CMOS

Here we can see, “How to Reset PC BIOS/CMOS”

This tutorial contains most major computer manufacturers, including Dell, HP, Asus, Acer, Lenovo, Toshiba, Samsung, and others.

How to Reset the BIOS (Basic Input/Output System)

Method 1: BIOS Menu

You may reset the BIOS directly from the BIOS menu by accessing it and looking for the Default Settings option.

To do so, take the following steps:

  1. Your computer should be restarted.
  2. Take note of the key; you must tap on the first screen. This key activates the BIOS menu, the “setup” utility.

Depending on your computer’s manufacturer, this key is commonly Esc, Del, F2, F8, or F12.

3. Locate the BIOS settings reset option. This option is commonly referred to as one of the following:

  • Load Default
  • Load Fail-Safe Defaults
  • Load BIOS Defaults
  • Load Default Settings
  • Load Setup Default
  • Get Default Values

4. Save the changes you’ve made.

5. Exit the BIOS setup.

Method 2: Clear the jumper

A specific jumper on your computer’s motherboard can clear the BIOS saved settings and restore them to their original defaults.

You may also reset the BIOS menu password by clearing the jumper.

To do so, take the following steps:

  1. Turn off your computer.
  2. To turn off the computer, turn off the power switch.
  3. Make sure you’re on solid ground. Static discharges have the potential to harm your computer.
  4. Locate a jumper on the motherboard with a name similar to one of the following. (The CMOS battery is generally at this jumper.)
  • CLEAR CMOS
  • CLEAR
  • CLR CMOS
  • CLR PWD

5. Make sure the jumper is in the Clear/CLR position.

6. Start your computer by turning it on.

7. Turn your PC off and return the CLR jumper to its original position after booting. Otherwise, your settings (including clock) would be reset every time you reboot!

Method 3: Replace the CMOS battery

If Method 2 doesn’t work (because your computer lacks the necessary jumper), you can try removing and replacing the CMOS battery. If your computer has a CMOS battery, this approach will work, and that battery isn’t found on all motherboards. Instead, take these procedures to reset the BIOS by changing the CMOS battery:

  1. Turn off your computer.
  2. Remove the power cord from your computer to ensure that it is not receiving any electricity.
  3. Make sure you’re on solid ground. Static discharges have the potential to harm your computer.
  4. On your motherboard, look for the battery.
  5. Take it out. If the battery won’t slide easily, abandon this approach and try Method 1 or Method 2 to reset the BIOS.
  6. Allow 5 to 10 minutes for the process to complete.
  7. Reinstall the battery.
  8. Turn your PC on.

User Questions:

1. What is the procedure for resetting the BIOS on my computer?

  • Turn off your computer.
  • Restart your computer and press the key that takes you to the BIOS setup screen.
  • To reset the machine to its default, fall-back, or factory settings, use the arrow keys to browse the BIOS menu.
  • Your computer should be restarted.

2. Is cleaning CMOS the same as resetting BIOS?

While resetting the BIOS does not clear the CMOS, cleaning the CMOS does restore the BIOS settings to their original state. Clearing the CMOS is recommended when changing hardware (RAMs, graphics card, CPU) or when the BIOS can’t be accessed (system won’t start) due to an incorrect setting.

3. What should I do if my BIOS is corrupted?

Check to see if the manufacturer’s guarantee still covers your computer.

  • Use the backup BIOS to start the computer (Gigabyte motherboards only).
  • Remove the dedicated graphics card from the system.
  • The BIOS should be reset.
  • You should update your BIOS.
  • The BIOS chip should be replaced.
  • Replace the motherboard if necessary.

4. What is the purpose of resetting the CMOS?

Clearing the CMOS on your motherboard will restore your BIOS settings to factory defaults, which are the settings that the motherboard manufacturer determined would be used by the majority of customers. One purpose of clearing CMOS is to aid in the diagnosis and resolution of computer faults or hardware compatibility concerns.

5. What is the best way to check for BIOS issues?

Using the System Information Panel, check your BIOS version. The version number of your BIOS can also be found in the System Information box. Hit Windows+R, type “msinfo32” into the Run box, and press Enter on Windows 7, 8, or 10. On the System Summary pane, the BIOS version number is displayed.
