How to remove BIOS password


WHAT IS BIOS PASSWORD?

Bios password information is normally store on a CMOS battery. Bios password is a type of security protection measure to stop unauthorized person making hardware configuration changes on system devices (Example: BIOS’s allow you to require a password to be entered before the BIOS setup may be accessed) Meanwhile, bios password also use security protection such as Some BIOS’s allow you to require a password be entered before the system will boot.



Forgot your motherboard BIOS password? No problem!!!!!!!!Here are three tutorials how to reset or remove Bios Password that allow clear your CMOS password. The first method is removing the battery on motherboard and second method is reset bios password on windows.



To remove the bios password on CMOS battery, first you need unplug all the power source and USB cable. Then open the desktop casing and allocate the flat, circular and metallic CMOS battery. It should look something like the picture to the right.This reset bios password is more suitable for desktop user. It is no recommended for laptop user unless you are experienced working with laptop hardware or the laptop warranty expired long time ago.Once allocated, take out the CMOS battery and wait 10 – 25 minutes before putting it back in. The reason for this wait is because the computer can still store power in its capacitors even though everything is unplugged. The waiting period allows enough time for them to discharge.After that, Plug back the CMOS battery. Then all bios password will be clear and all computer devices hardware setting will be set factory default setting. In some cases, if you get weird error messages during bootup now, you will need to goto “Load BIOS Defaults” in BIOS and save the changes to fix them.
