Resetting the Setup and Power-on password
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!
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.
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.
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
Regulatory, Safety and Environmental Notices
guide
for more information.
3.
Remove the rear cover.
4.
Locate the header and jumper labeled PSWD.
NOTE:
The password jumper is blue so that it can be easily identified. For assistance locating
the password jumper and other system board components, see the Illustrated Parts & Service Map
(IPSM). The IPSM can be downloaded from
http://www.hp.com/support
.
5.
Remove the jumper.
6.
Replace the jumper.
7.
Replace the rear cover.
8.
Reconnect the external equipment.
9.
Plug in the computer and turn on power. Allow the operating system to start. This clears the current
passwords and disables the password features.
10.
Establish the new passwords in Computer Setup. See
Computer Setup (F10) Utility on page 90
for
information.
