This computer supports two security password features, which can be established through the Computer
Setup Utilities menu: supervisor password and user password
To disable the password features, or to clear the 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.
3.
Remove the computer cover or access panel.
4.
Locate the header and jumper.

For assistance locating the password jumper and other system board components, see

from http://www.hp.com/support.
