You need to set a jumper on the motherboard to drain the cmos power. this removes the bios password.

I suggest googling it with your laptop model.

According to Lenovo, you must take it in for service to reset the password:

However, the second post at this link describes a way to do it yourself:

The x120e is a business machine with the password stored in non-volatile RAM (NVRAM) not in the CMOS, so a CMOS reset will only restore the laptop settings it won't remove the password and as NVRAM doesn't require power to retain its contents pulling the batteries won't help either.  You'll need to get Lenovo involved and prove ownership for them to reset at a cost.

It's not in the S20 class that the link above describes.

You can't remove the password, without knowing it !   -->  ( what good is a password that can be "repaired" ?)
modern laptops keep it in a security chip - for anti-theft reasons
resetting the bios does not help;  nor does removing the battery, since the password is not in there
you would need to know in what chip it is, and how to reset that
you have to turn it in to the manufacturer, and show proof of ownership - then they can help
or replace the mobo !
