How To Reset BIOS Without Display – Step by Step

In some cases, you may not be able to access the BIOS settings due to a display problem. Here are the steps you can take to reset the BIOS without a display:

1: Shut down your computer

The first step is to shut down your computer properly. Press and hold down the power button on your computer for 5 to 10 seconds until it shuts down completely.

2: Disconnect the power supply and other external devices

Once your computer has been shut down, unplug the power cable from the back of your computer. Also, remove any other external devices that are connected to your computer, such as a printer or scanner.

3: Open the computer case

Locate the screws that are holding the side panel of your computer case in place. Use a screwdriver to take out these screws and gently slide the panel off to expose the inside of your computer.

4: Locate the CMOS battery

The CMOS battery is round battery located on the motherboard. It stores the BIOS settings and keeps the system clock running even when the computer is turned off. Identify the battery on the motherboard and gently remove it using a screwdriver or your fingers.

5: Wait for a few minutes

After removing the CMOS battery, wait for a few minutes. This allows the residual charge in the motherboard to dissipate, which ensures that the BIOS is fully reset.

6: Replace the CMOS battery

Once you’ve waited for a few minutes, reinsert the CMOS battery into its slot on the motherboard. Ensure that the battery is inserted correctly and that it makes good contact with the motherboard.

7: Reassemble your computer

8: Enter the BIOS setup

When you turn on your computer, it will boot up into the BIOS setup. You may need to press a specific key to enter the BIOS setup, such as F2, F12, or Delete, depending on your computer’s manufacturer. Check your computer’s documentation to determine which key to press.

9: Load default BIOS settings

Once you’re in the BIOS setup, locate the option to load default BIOS settings. This option may be labeled as “Load Optimized Defaults” or “Load Setup Defaults.” Choose this option to load the default settings for your BIOS.

10: Save and exit BIOS

After loading the default BIOS settings, save the changes and exit the BIOS setup. Your computer should now be reset, and the display issue should be resolved. Some motherboards have a clear CMOS jumper that you can use to reset the BIOS. Check your motherboard manual for more information on this process. In some cases, resetting the BIOS may not solve the problem. If this is the case, you may need to replace the CMOS battery or seek professional help to diagnose the issue.

It is important to note that resetting the BIOS will erase any custom settings you have configured, such as boot order, overclocking settings and password protection. You will need to reconfigure these settings after resetting the BIOS.
