How to Change/Reset a BIOS password Posted on 30 December 2008
Tags: Tech News, Tutorials If you are a normal computer user who has forgot his BIOS password and you are unable to access to your BIOS, then you need a simple way to change your BIOS. Its not that hard because you just need a simple trick to reset your BIOS password.
Open your CPU cabinet after switching OFF the power and then try to locate the CPU battery which can be found very easily. Once you locate your battery you need to remove it once and restart your PC without the battery.

Note : Once you remove your battery from the mother board, you will find that all your time settings in your computer would be lost, and some softwares may stop working which are based on your computer time.


You need to shut down your PC again and now add back the battery which will enable you the time saving feature and also reset your BIOS password.

There is no generic BIOS password. If there is one on your computer then someone set it up. If you cannot find that person or remember what it is then you need to reset the BIOS. To reset the BIOS you need to remove all power from the system. Then you will need to open up the notebook to get access to the motherboard to find the BIOS battery which will look like a large watch battery. Remove that for about 1 minute. Then replace everything and start up again.
