Resetting the Password Jumper

To disable the power-on or setup password features, or to clear the power-on or setup passwords, complete the following steps:

1.Shut down the operating system properly, then turn off the computer and any external devices, and disconnect the power cord from the power outlet.

2.With the power cord disconnected, press the power button again to drain the system of any residual power.

ÅWARNING: To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to disconnect the power cord from the wall outlet, and allow the internal system components to cool before touching.

ÄCAUTION: When the computer is plugged in, the power supply always has voltage applied to the system board even when the unit is turned off. Failure to disconnect the power cord can result in damage to the system.

ÄCAUTION: Static electricity can damage the electronic components of the computer or optional equipment. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. See the Safety & Regulatory Information guide on the Documentation CD for more information.

3.Remove the computer cover or access panel.

4.Locate the header and jumper.
