How to Reset or Remove Bios Password

Submitted by on 16 Apr 2011 5 Comments

Many people use BIOS password to lock up their computers, making them completely unusable without entering the correct password. This password has to be entered before loading the operating systems, normally on a DOS screen shortly after the computer started. BIOS password is usually stored together with other BIOS settings such as the time, date, size of hard disk, etc. These pieces of data are usually stored in a flash chip on the motherboard.

To reset or remove the BIOS password, look for a jumper which usually can be found near the processor or BIOS battery on the motherboard. After locating the jumper (usually with a label – PSWD beside it), move the jumper from connected pins 1+2 to pins 2+3 for a few seconds or so, then move back to pins 1+2. This will reset the entire BIOS settings. The next time you boot your computer, the BIOS will show you the default factory settings and from there you can optionally set a new password.

If you’re either not allowed to touch the motherboard or can’t find any jumper on the motherboard, you can reset or remove the bios settings via DOS if you have access to it.

Here’s how you can do it:

Type debug

‘Type o 70 2e

Type o 71 ff

Type q

Taa da! Your machine’s Bios has been reset. Restart your computer now and everything should run just fine.

Another alternative way to completely reset your bios setting is to re-insert the CMOS battery which can be found on the motherboard. The CMOS battery provides power supply to the motherboard in order to hold the Bios Setting data. That said, when you remove the CMOS battery, everything stored will be reset to the factory default setting. You can do this when you have no access to DOS.

    I know some methods to reset bios password.
    1. The best and easiest method: Close OS and shut down the electricity power of computer. Open your computer box, take out the cmos battery from the mainboard. Then the bios password will be reset to blank. Put it back after a few minutes.
    2. Follow some tutorials. For example the tutorials:

    I tried to go into the BIOS setup utility and i manage to create a BIOS password, but the problem is that the password will only prompt when i want to enter the BIOS setup, not during the boot up. I looked everywhere in the setup but i just couldn’t find the settings to set the password to promp at boot up.

    This is a password hack but it clears the BIOS such that the next time you start the PC, the CMOS does not ask for any password. Now if you are able to bring the DOS prompt up, then you will be able to change the BIOS setting to the default. To clear the CMOS do the following:
    Get DOS prompt and type
