How to Reset BIOS: A Complete Guide to Restoring BIOS Settings

Resetting your BIOS can be a helpful solution for resolving hardware issues, resetting a forgotten BIOS password, or restoring settings to factory defaults. The process varies depending on your motherboard's make and model, but there are several universal methods suitable for most cases. Let’s go over each one in detail.

Method 1: Resetting BIOS Through the BIOS Menu

The easiest way to reset BIOS settings is directly from the BIOS menu. Follow these steps:

  1. Turn on or restart your computer, and immediately press the Del, F2, F10, or Esc key (depending on your device model) to enter the BIOS setup.
  2. Locate the section with options like Load Setup Defaults, Reset to Default, Factory Reset, or something similar.
  3. Select the option and confirm the reset. This will return BIOS settings to their factory defaults.

Method 2: Resetting BIOS Using the Jumper on the Motherboard (Clear CMOS)

If you can’t access the BIOS menu, you can use the jumper on the motherboard to reset it:

  1. Disconnect the computer from power and remove the case cover.
  2. Locate the jumper labeled CLRTC, CLR CMOS, or JBAT1 on the motherboard (label may vary).
  3. Move the jumper to the reset position for about 5–10 seconds, then return it to its original position.
  4. Reconnect the power and turn on the computer.

This method clears the CMOS and resets BIOS to its factory defaults.

Method 3: Resetting BIOS by Removing the Battery

Another way to reset BIOS settings is by removing the CMOS battery. Here’s how:

  1. Turn off your computer and open the case.
  2. Locate the round CMOS battery on the motherboard (usually a CR2032 battery).
  3. Carefully remove the battery and wait 5–10 minutes.
  4. Place the battery back, reconnect power, and turn on the computer.

This method also resets all BIOS settings.

Potential Consequences and Precautions

Be aware that resetting the BIOS will delete all custom settings, including boot order, processor settings, and manually configured memory values. After a reset, it's recommended to review and adjust BIOS settings as needed.

Important! Always ensure your computer is fully disconnected from power before performing any hardware adjustments to avoid equipment damage or injury.
