Resetting The Password Jumper - HP Compaq dc5750 MT Troubleshooting Manual

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.
WARNING!
be sure to disconnect the power cord from the wall outlet, and allow the internal system
components to cool before touching.
CAUTION
to the system board even when the unit is turned off. Failure to disconnect the power cord
can result in damage to the system.
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 Hardware Reference
Guide on the Documentation and Diagnostics CD for more information.
3. Remove the computer cover or access panel.
4. Locate the header and jumper.
NOTE
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
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.
8. Plug in the computer and turn on power. Allow the operating system to start. This clears the current
passwords and disables the password features.
9. To establish new passwords, repeat steps 1 through 4, replace the password jumper on pins 1 and
2, then repeat steps 6 through 8. Establish the new passwords in Computer Setup. Refer to the
Computer Setup (F10) Utility Guide on the Documentation and Diagnostics CD for Computer Setup
instructions.
