I forgot my bios password in my pc

Bios password cannot be gained back. If you have forgotten the password then you have to reset the nvrm which will reset the password.

I work in a computer and printer service center and have enough experience on this issue.

This is what I tried long back... Remove the bios battery if possible wait for a few minutes and put it again ...
