If we forget the BIOS Password, it might be very hard to crack (because no software can be used). So, we just reset EVERYTHING.

For Noobs: BIOS password is the password which can be set on the BIOS setup (The Black or Blue dull screen), not on the Operating System.

How it Works?

Even if you shut your PC down, it remembers the settings all with the help of a battery. With this off the circuit for a while, it forgets it all, even the password :D .

Procedure:

Power down and open up your Computer. You can see a battery (see picture). Remove it, put it back after about 5 seconds.

Motherboard Battery

Now, switch on your computer. You will greeted with an error – “’Checksum Wrong, Settings Wrong etc”. You just press load optimized defaults (F1, F2 Delete…Whatever).

You’re Done!! :)

Nowadays there is a trend of buying USB keyboards. If you do own one, you  might be in a situation, where you’ll have a  USB keyboard disabled in the BIOS (Might be because of a BIOS update or some other reason)
With USB keyboard not working on the BIOS and no way to enable it, this is a real head scratcher..
Here’s the fix,
1) Open up your PC
2) Look for the BIOS jumper

3) If the jumper is on pin 1 and pin 2 its in the normal mode. (It will most probably be in this mode)
4) Switch the jumper to pin 2 and pin3 that is, recovery mode.
5) Boot up the PC
6) You will be welcomed with the bios screen. Now, you can work with the USB keyboard (Yes!)
7) Now, see to it that, USB Legacy mode is Enabled.
8) Select Save settings and shut down the machine.
9) After that, switch the jumper back to its original position.
Voila, Its done, and you’re all set to go. :)
