How to remove a Bios Password
This page will give you three ways in which you can remove a bios password. The first is using bios password removers, demonstrated in the video below.
This was a video response to a question that was left in the comments section of one of my videos. Unfortunately, using bios removal utilities, like the ones on the Hiren's BootCD, is often unsuccessful and, in rare cases, can damage your motherboard. These should always be a last resort and used with caution, so here are some other ways that I suggest to try before using these programs.
Removing the CMOS battery
The first and most effective method that you can try is removing the CMOS battery on your motherboard, leaving it out for about 20-30 minutes, and then replacing it. Don't forget to completely power off your comptuer and leave it for a while before opening up your computer and removing it. This usually resets the bios password and is the most common way to do so. This does require you to open up your computer of course, but it is quite simple and easy to do. Below are two pictures of where the cmos is typically found on the motherbaord and a close-up shot of the CMOS battery. To release the CMOS battery, gently push the metal prong, shown in the picture to the right. Leave it out for approximately 10 minutes and then replace it. This will usually remove a bios password.
The second thing to try is using default passwords. These are some of the default Bios passwords used with different Bios's. Some of them will even override your old password allowing you to enter and reset or change it so these main ones are worth trying:
AMI_SW (case sensitive)
NOTE: With respect to the Award BIOS, the "AWARD_SW" (use without quotes) and (is case sensitive) password should even override a set password! If not, you may also want try j262 as the password.
