|Your Lenovo has two passwords - Hard drive password & Power-on password. It is NOT possible to reset the password through a jumper configuration, or taking the CMOS battery out. There are only two methods of resetting the password: |
1. Call up the laptop manufacturer, with the serial number of the machine, and proof of purchase. You will then be given a machine-specific supervisor password to unlock your machine.
2. If you have no proof of purchase for any reason, OR your machine can not be verified as legit, the bank on the best part of $200 to get it unlocked. In extreme cases, a new motherboard has to be installed.
