4. Locate the header and jumper labeled CLR_PASS.
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 from pins 2 and 3.
6. Place the jumper on pins 1 or 2.
7. Put the jumper back on pins 2 or 3.
8. Replace the access panel.
9. Reconnect the external equipment.
10. Plug in the computer and turn on power. Allow the operating system to start. This clears the
current passwords and disables the password features.
11. To establish new passwords, use Computer Setup.
Clearing and Resetting the CMOS
The computer’s configuration memory (CMOS) stores information about the computer’s configuration.
The CMOS button resets CMOS but does not clear the power-on and setup passwords.
Clearing CMOS will clear the Active Management Technology (AMT) settings in the Management
Engine BIOS Extension (MEBx), including the password. The password will default to “admin” and will
need to be reset. The AMT settings will also need to be reset. To access the MEBx, press Ctrl+P
during POST.
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 Safety & Regulatory Information guide for more
information.
