Hacking your BIOS password

Genie BIOS Settings - 2.jpg

A key component of you computer is the BIOS. It contains specific instructions as to how your whole computer will behave thus it is quite crucial that this is protected at all times.One very common way of protecting your BIOS is by using the Password utility that is incorporated with the BIOS itself. By using the password, any unauthorized entries are eliminated thus no one can change the BIOS settings by mistake or maliciously.

The problem that is quite common with this solution though is the simplest but also the most irritating – forgetting the password itself. When you forget your BIOS password you cannot enter it anymore so if something goes wrong with your computer you cannot effect any changes on the BIOS itself. This is potentially a very catastrophic problem.

Fortunately, there are certain steps that you can do to solve this problem.

For motherboards that have been manufactured before Dec. 19, 1996, there are default passwords that you can actually use. The default password is usually the initials of the manufacturer’s name or such passwords as AWARD?SW, AWARD?PW, LKWPETER, 589589, aLLy, condo, djonet, lkwpeter, among others. But if these passwords do not work or if your motherboard is manufactured after 1996 (which it most likely is), then another option would be to discharge the CMOS. Waiting for the CMOS to drain is, of course, not recommended because it may take five to ten years for it to drain (and by that time you’ll probably have upgraded anyway). The most common way of draining it is to remove the CMOS chip or the battery and then wait for twenty minutes before installing it again.

Another option is to flood the keyboard buffer in order to crash the password routine. When you reach the password prompt just continuously press the ESC key.

  1. You could also move the cmos jumper from pins 1 and 2 to 2 and 3 (usually the standard). Of course you want to do this when the computer is off, wait about twenty seconds, then put it back in the original position. This will usually reset the bios to its factory setting. Likewise this means you have to reconfigure all of your settings.

  2. My laptop (dell inspiron 3800) doesn’t have a CMOS jumper. IS there anything I can do to reset this in my case?
