BIOS password is used to add some extra security to computers. You can either set a password to prevent access to BIOS settings or to prevent PC from booting. But sometimes this extra security might become a pain when you forget the BIOS password or someone changes your system BIOS password intentionally. But there is no need to worry. There are many known ways to reset / remove / Bypass the BIOS password.
1. By removing the CMOS battery
2. By using the motherboard jumper
3. By using MS DOS command
4. By using Backdoor BIOS password.

Now All the methods are explained below one by one:
By removing the CMOS battery:Almost all motherboards use a small coin sized CMOS battery to store all BIOS settings along with the password. To reset the password, unplug the PC, open the cabinet and remove the CMOS battery for 15-30 minutes and then put it back. It will reset all BIOS settings as well as the password and you will need to re-enter all settings. If it fails then try to remove the battery for at least one hour.
By using motherboard jumper:Almost all motherboards contain a jumper that can clear all CMOS settings along With the BIOS password. The location of this jumper varies depending upon the Motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS Battery. Most of the manufacturers label the jumper as CLR, CLEAR, CLEAR CMOS, Etc.When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, Is removing the jumper and join the center pin to the opposite pin.
e.g: If the jumper joins center pin to left pin, then remove it and join center pin to right Pin. Now wait for a few seconds and then again remove the jumper and join the Center pin to left pin.Make sure to turn the PC off before opening the cabinet and resetting the Jumper.
By using MS DOS command:This method work only when you have access to the system when it turned on because this requires MS DOS. Open Command Prompt from program and enter following one by one.
debug
o 70 2E
o 71 FF
quit
NOTE: The first character in the above commands is "O" and not the number 0.After providing the above commands, restart your system and it should reset the CMOS Settings along with the BIOS password. If you are curious to know how it works? Then let me explain the above commands: In this method we are using the Debug tool of MS DOS. The "O" character present At first in these commands, outputs the values to IO ports. The number 70 and 71 Are port numbers which are used to access CMOS memory. By providing FF value we are telling CMOS that there is an invalid checksum and it resets the CMOS
Settings as well as BIOS password.
By using backdoor BIOS password:Some BIOS manufacturer put a backdoor password in BIOS which always works Irrespective of what password you have set in BIOS. It’s a master password which Is used for testing and troubleshooting purposes.
