How to Reset or Remove a BIOS Password: 5 Effective Methods

BIOS passwords can provide an extra layer of security for your computer, but they can also become a major headache if forgotten. Whether you’re dealing with a locked-out system or simply need to regain access, there are several methods you can try to reset or remove a BIOS password. Let’s explore five effective approaches, starting with the most reliable and least invasive options.

Method 1: Use BIOS Password Backdoors

Many BIOS manufacturers have built-in backdoor passwords that can bypass the set password. This method is often the quickest and safest way to regain access to your system.

Step 1: Attempt to enter the BIOS by pressing the appropriate key during startup (usually Del, F2, or F10).

Step 2: Enter an incorrect password three times. This should trigger a system lockout and display a code or checksum.

Step 3: Visit the website bios-pw.org and enter the displayed code.

Step 4: Try the generated passwords provided by the website, starting with the one matching your BIOS manufacturer.

If successful, you’ll regain access to the BIOS. Remember to remove or change the password once you’re in.

Caution: This method works on many systems but isn’t guaranteed for all BIOS versions or manufacturers.


Method 2: Clear CMOS Settings

Clearing the CMOS (Complementary Metal-Oxide-Semiconductor) can reset all BIOS settings, including passwords. This method is more invasive but often effective.

Step 1: Shut down your computer and unplug it from the power source.

Step 2: Open the computer case to access the motherboard.

Step 3: Locate the CMOS battery on the motherboard. It’s typically a small, silver, coin-shaped battery.

Step 4: Carefully remove the CMOS battery.

Step 5: Wait for about 5-10 minutes, then reinsert the battery.

Step 6: Reassemble your computer and power it on.

The BIOS should now be reset to its default settings, clearing any passwords.

Note: On some modern systems, removing the CMOS battery may not clear the password. In such cases, proceed to the next method.


Method 3: Use BIOS Password Reset Jumper

Many motherboards have a dedicated jumper for clearing BIOS passwords. This method is more reliable than removing the CMOS battery on newer systems.

Step 1: Shut down and unplug your computer.

Step 2: Open the case and locate the password reset jumper on the motherboard. It’s often labeled as “CLEAR_PWD”, “CLR_CMOS”, or something similar.

Step 3: Move the jumper from its default position to the “clear” position (usually connecting the middle pin to the opposite pin from the default).

Step 4: Wait for about 30 seconds, then move the jumper back to its original position.

Step 5: Reassemble your computer and power it on.

The BIOS password should now be cleared.

Caution: Consult your motherboard manual for the exact location and procedure for your specific model.


Method 4: Try Default BIOS Passwords

Some BIOS manufacturers use default passwords that can bypass user-set passwords. While not as common or reliable as the previous methods, it’s worth trying if other approaches fail.

Common default passwords include:

  • admin
  • password
  • BIOS
  • setup
  • The PC’s serial number

Try these and any others specific to your computer’s manufacturer.

Note: This method is less likely to work on modern systems but can be effective on older computers.


Method 5: Use BIOS Password Cracking Software

As a last resort, you can try specialized software designed to crack BIOS passwords. This method is more complex and potentially risky, so proceed with caution.

Step 1: Research and download a reputable BIOS password cracking tool like CmosPwd.

Step 2: Create a bootable USB drive with the password cracking software.

Step 3: Boot your computer from the USB drive.

Step 4: Follow the software’s instructions to attempt to crack or bypass the BIOS password.

Warning: Only use this method if you’re confident in your technical skills and understand the potential risks. Some tools may violate your computer’s warranty or legal terms of use.


Resetting a BIOS password can be tricky, but with these methods, you should be able to regain access to your system. Always start with the least invasive options and progress to more complex solutions if needed. If all else fails, consider seeking help from a professional technician who may have specialized tools for BIOS password removal.
