Disabling the Setup Password If the Current Password Has Been Lost
Power down your PC and disconnect the main power cord. Open the computer case and touch a metal surface on the outer casing of the computer to ground yourself, preventing damage to any internal components.
Look on the green motherboard for a small plastic "jumper" block connecting two pins labelled "PSWD." Carefully remove the jumper block connecting the two pins. Replace the PC cover and re-connect the computer's power cord.
