Resetting the password jumper
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.
3. Remove the access panel.
4. Locate the header and jumper.
5. On systems with 3-pin jumpers, remove the jumper from pins 1 and 2. Place the
jumper on pins 2 and 3. On systems with 2-pin jumpers, remove the jumper from pins
1 and 2.
6. Replace the access panel.
7. Reconnect the external equipment.
8. Plug in 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 - 4, replace the password jumper on pins
1 and 2, then repeat steps 6 - 8. Establish new passwords in Computer Setup.
Clearing and Resetting the CMOS
To provide a jumper to trigger reloading of all BIOS Setup default values. Once the

"Default BIOS settings have been loaded."
1. Turn off the computer and any external devices, and disconnect the power cord from
The power outlet.
2. Disconnect the keyboard, monitor, and any other external equipment connected to the
computer.
3. Remove the access panel.
4. Locate the header and jumper.
CAUTION: Make sure you have disconnected the AC power cord from the wall
outlet. Clearing the CMOS while power is connected can damage the system board.
5. Remove the jumper from pins 1 and 2. Place the jumper on pins 2 and 3.
6. Place the jumper back on pins 1 and 2.
7. Replace the access panel.

Hewlett-Packard Vision Diagnostics
The Hewlett-Packard Vision Diagnostics utility allows you to view information about the
hardware configuration of the computer and perform hardware diagnostic tests on the
subsystems of the computer. The utility simplifies the process of effectively identifying,
diagnosing, and isolating hardware issues.
Use HP Vision Diagnostics to determine if all the devices installed on the computer are
recognized by the system and functioning properly.
To access HP Vision Diagnostics, you must create a Recovery Disc Set then boot to the
CD containing the utility. It can also be downloaded from http://www.hp.com and
either burned to CD or installed to a USB flash drive.

System Recovery
System Recovery completely erases and reformats the hard disk drive, deleting all data
files you have created, and then reinstalls the operating system, programs, and drivers.
However, you must reinstall any software that was not installed on the computer at the
factory. This includes software that came on media included in the computer accessory
box, and any software programs installed after purchase.
You must choose one of the following methods to perform a System Recovery:
* Recovery Image. Run the System Recovery from a recovery image stored on your hard
disk drive. The recovery image is a file that contains a copy of the original
factory-shipped software.
NOTE: The recovery image uses a portion of the hard disk drive that cannot be used
for
data storage.
* Recovery Discs. Run the System Recovery from a set of recovery discs that you create
from files stored on your hard disk drive or purchased separately.
