Hi



BIOS passwords can be reset in two ways,
1. using software 2. using hardware.

I would first try resetting using software, here are two software's to reset or retrieve BIOS passwords.

!BIOS - is a PC BIOS toolkit offering password removal/decrypt and BIOS settings modification/backup/restore.

CmosPwd - Cmos password recovery tools

Please let us know if it works

To reset the BIOS follow my instructions from this link: http://www.fixya.com/support/r7229632-reset_or_remove_bios_password

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.

The BIOS one can usually be eliminated  by disconnecting the battery and shorting the terminals, if necessary, then plugging the battery back in.    The administrator pass work can sometimes be gotten around by pressing the F8 while loading,then changing it.   The most undesirable option is to reformat and buy another OS.   Sorry for the hard time.
