How To Reset Your Bios Password

There is nothing more annoying than starting up your desktop or laptop computer only to be halted by a password request. Aside from the fact that this slows down your start-up some people do not even remember or know their passwords.

Fortunately BIOS passwords are very often easily fixable. The most obvious way to reset your password is to open up your computer case and locate the battery on the Mother Board. Most of these batteries are going to look like watch batteries (See Photo.)

Before you begin the reset process, be certain you are properly discharged of static electricity and go to work removing the side cover on your computer. Once this is achieved you will have to unplug the computer AC and then remove the BIOS battery. (See photo for most common type.) After removing the battery wait about one minute and then replace the battery the same way it came out. You should then have successfully reset the password and the computer should reboot fine with the defalt Bios Setings. If your Bios Settings did not come up coorectly you can change them by pressing the command that allows you to access the programming page. Us computer techs ge there by looking at the bottom of the computer start-up screen and pressing either one of these usual commands. (Delete (Key) F1 (Key) or the F10 (Key))

Laptop computers usually work the same way with one very big exception and that is the battery is hard to get to, as it is inside the computer case. If you are not good at taking things apart and putting them back together you may want to call the ComputerFox Inc. in your area to do this for you. However, if you feel brave you will in most cases find the battery either wrapped in plastic with a red and black pigtail on it attached to the mother board, or in some rare cases it may look like a desktop PC battery or be a small watch battery on the motherboard. In either case the method of resetting the password is the same, disconnect the internal battery, AC power and DC Power pack. Wait a minute put the power sources back in and this should fix the problem on your next start up.


If this did not fix the problem, as in the case of many IBM high security laptops you will have to contact the vendor of that laptop for specific instructions on how to create a jumper circuit to over-ride the BIOS password. (See photo for an example.) Some units also have removable bios chips, these chips can be affordably removed and replaced if they are in ZIF sockets like the one featured in the photo (Left.)

As a final note some motherboards and laptops may not have removable batteries, in those cases you may need to do some research to find the appropriate jumpers to reset the password.
