Clearing and resetting CMOS
The computer's configuration memory (CMOS) stores information about the computer's con-
figuration. The CMOS button resets CMOS but does not clear the power-on and setup pass-
words.
1. Turn off the computer and any external devices, and disconnect the power cord.
2. Disconnect the keyboard, monitor, and any other external equipment.
3. Remove the access panel.
4. Locate the header and jumper.
5. Remove the jumper from pins 1 and 2.
6. Place the jumper on pins 2 and 3.
7. Replace the access panel.
8. Reconnect the external devices.
9. Plug in the computer and turn on power.
NOTE: You will receive POST error messages after clearing CMOS and rebooting advising you
that configuration changes have occurred. Use Computer Setup to reset any special system
setups along with the date and time.
Resetting the password jumper
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.
2. With the power cord disconnected, press the power button again to drain 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 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.
Hewlett-Packard Vision Diagnostics
The Hewlett-Packard Vision Diagnostics utility allows you to view information about the hard-
ware 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 iso-
lating hardware issues.
Use HP Vision Diagnostics to determine if all the devices installed on the computer are recog-
nized by the system and functioning properly. Running tests is optional but recommended after
installing or connecting a new device.
To access HP Vision Diagnostics, you must create a Recovery Disc Set then boot to the CD con-
taining the utility. It can also be downloaded from http://www.hp.com and either burned to CD
or installed to a USB flash drive.
1. In Windows Explorer, go to C:\SWSetup\ISOs and burn the file Vision Diagnostics.ISO to a
CD or copy it to a USB flash drive.
2. While the computer is on, insert the CD in the optical drive or USB flash drive in a USB port.
3. Shut down the operating system and turn off the computer.
4. Turn on the computer. The system will boot into HP Vision Diagnostics.
NOTE: If the system does not boot to the CD in the optical drive or to the USB flash drive,
you may need to change the boot order in the Computer Setup (F10) utility.
5. At the boot menu, select either the HP Vision Diagnostics utility to test the various hardware
components in the computer or the HP Memory Test utility to test memory only.
NOTE: The HP Memory Test is a comprehensive memory diagnostic utility that is run as a
stand-alone application, outside of HP Vision Diagnostics.
6. If running HP Vision Diagnostics, select the appropriate language and click Continue.
7. In the End User License Agreement page, select Agree if you agree with the terms. The HP
Vision Diagnostics utility launches with the Survey tab displayed.

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 pro-
grams you 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 soft-
ware.
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.
Attempt a System Recovery in the following order:
1. Through the hard disk drive, from the Windows Start menu.
2. Through the hard disk drive, by pressing the F11 key on the keyboard during system startup.
3. Through recovery discs that you create.
4. Through recovery discs purchased from HP Support. To purchase recovery discs, visit http://
www.hp.com/support.

Choosing recovery discs
•
To create recovery discs, your computer must have a DVD writer, and you must use only
high quality blank DVD+R or DVD-R discs.
NOTE: You cannot use CDs or DVD+RW, DVD-RW, DVD+RW DL, DVD-RW DL,
DVD+R DL, or DVD-R DL discs to create recovery discs.
•
Use high-quality discs to create your set of recovery discs. It is normal for discs to be
rejected if they are not defect-free. You will be prompted to insert a new blank disc to try
again.
•
The number of discs in the recovery-disc set depends on computer model (typically 3-6
DVD discs). The Recovery Disc Creator program tells you the specific number of blank
discs needed to make the set.
NOTE: The process of creating recovery discs takes some time to verify that the information
written on the disc is correct. You can quit the process at any time. The next time you run the
program, it resumes where it left off.
Creating recovery discs
To create recovery discs:
1. Close all open programs.
2. Click the Start button, click All Programs, click Recovery Manager, and then click
Recovery Disc Creation. If prompted, click Yes to allow the program to continue.
3. Follow the onscreen instructions. Label each disc as you make it (for example, Recovery 1,
Recovery 2).
