Password Security and Resetting CMOS
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.
Å
WARNING: 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.
Ä
CAUTION: 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.
Ä
CAUTION: 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.
✎
The password jumper is green so that it can be easily identified. For
assistance locating the password jumper and other system board
components, see the Illustrated Parts Map (IPM) for that particular
system. The IPM can be downloaded from www.hp.com/support.
5. Remove the jumper from pins 1 and 2. Place the jumper on either
pin 1 or 2, but not both, so that it does not get lost.
6. Replace the computer cover or access panel.
7. Reconnect the external equipment.
