Reset BIOS password

BIOS passwords are used to add some more security to your computers . As BIOS is not regularly used , you might forget bios password . So here is a trick to reset or break any BIOS password .

METHOD 1 

Remove and reset the BIOS battery or the BIOS cell form the mother board . You need to remove it for a few hours and then replug it . Do not know what and where the battery is ? just check the photo and find it on ur motherboard .

After that just follow the steps given below.

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 remove 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.

METHOD 2

This method works only if you have access to the system when its turned on because this method requires MS DOS. Open Command Prompt from Programs menu and provide following commands.
debug 
o 70 2E 
o 71 FF 
quit 
After providing the above commands, restart your system and it should reset the CMOS Settings along with the BIOS password.
