How To Remove or Clear bios password?

This information is intended for experienced users. It is not intended for basic users, hackers, or computer thieves. Please do not try any of following procedures if you are not familiar with computer hardware. I'll not be responsible for the use or misuse of this information, including personal injury, loss of data or hardware damage. So use it at your own risk.

A. By Using the Motherboard Jumper:

In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.

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 manufacturer 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.

 

B. By Using Software:


I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

Some require you do this 3x and it gives a lockout code that you can tell us and we can get a reset code to remove the bios password. If 3x doesn't work you might have to contact a MODerator on here and ask them if there is some other steps to try.

Re: How To Remove or Clear bios password?

Please.... This a laptop/notebook subforum. There are no jumpers on laptop's systemboard to remove any passwords. TS should have post this in a desktop subforum, perhaps there they still use jumers to remove the passwords. On a laptop systemboard you will never find a jumper to do so. Alex
