Recovering the Configuration Settings

This method of recovery requires that you first perform the Save to Removable Media
command with the Computer Setup (F10) Utility before Restore is needed.
NOTE: It is recommended that you save any modified computer configuration settings to a USB
flash media device or a diskette-like device (a storage device set to emulate a diskette drive) and
save the device for possible future use.

To restore the configuration, insert a USB flash media device or other storage media emulating a
diskette with the saved configuration and perform the Restore from Removable Media
command with the Computer Setup (F10) Utility.

Drive Protection System

The Drive Protection System (DPS) is a diagnostic tool built into the hard drives installed in
some computers. DPS is designed to help diagnose problems that might result in unwarranted
hard drive replacement.
Running DPS will not affect any programs or data stored on the hard drive. The test resides in
the hard drive firmware and can be executed even if the computer will not boot to an operating
system. The time required to execute the test depends on the manufacturer and size of the hard
drive; in most cases, the test will take approximately two minutes per gigabyte.
Use DPS when you suspect a hard drive problem. If the computer reports a SMART Hard Drive
Detect Imminent Failure message, there is no need to run DPS; instead, back up the information
on the hard drive and contact a service provider for a replacement hard drive.

Accessing DPS through Computer Setup

1. Turn on or restart the computer.

2. When the F10 Setup message appears in the lower-right corner of the screen, press the F10.

3. Select Storage > DPS Self-Test.

4. Select the hard drive to be tested and follow the screen prompts to complete the testing
process.

Password Security

This computer supports security password features, which can be established through the
Computer Setup Utilities menu.
This computer supports two security password features that are established through the
Computer Setup Utilities menu: setup password and power-on password. When you establish
only a setup password, any user can access all the information on the computer except Computer
Setup. When you establish only a power-on password, the power-on password is required to
access Computer Setup and any other information on the computer. When you establish both
passwords, only the setup password will give you access to Computer Setup.
When both passwords are set, the setup password can also be used in place of the power-on
password as an override to log in to the computer. This is a useful feature for a network
administrator.
If you forget the password for the computer, you can clear that password so you can gain access
to the information on the computer by resetting the password jumper.
CAUTION: Pushing the CMOS button will reset CMOS values to factory defaults.

Resetting the password jumper

1. Shut down the computer.

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. Remove the jumper from pins 1 and 2. Place the jumper on either pin 1 or 2, but not both.

6. Replace the access panel.

7. Plug in and turn on power. Allow the operating system to start. This clears the current
passwords and disables the password features.

8. 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

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. Turn off the computer and any external devices, and disconnect power.

2. Remove the access panel.

3. On the system board, press and hold the CMOS button for 5 seconds.

4. Replace the access panel, external devices, and reconnect the power cord.

5. Turn on the computer.

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.

HP Vision Field Diagnostics

The Hewlett-Packard Vision Field 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.
The Survey tab is displayed when you invoke HP Vision Field Diagnostics. This tab shows the
current configuration of the computer. From the Survey tab, there is access to several categories
of information about the computer. Other tabs provide additional information, including diag­nostic test options and test results. The information in each screen of the utility can be saved as
an html file and stored on a diskette or USB flash drive.
Use HP Vision Field Diagnostics to determine if all the devices installed on the computer are
recognized by the system and functioning properly. Running tests is optional but recommended
after installing or connecting a new device.
Vision Field Diagnostics may be found on the CD that shipped with some computer models.
The tool may also be downloaded from the HP Web site using the following procedure:

1. Go to www.hp.com

2. Click the Software & Download driver link.

3. Select Download drivers and software (and firmware).

4. Enter the product number in the text box and press Enter.

5. Select the specific product.

6. Select the OS.

7. Click the Diagnostic link.

8. Click Hewlett-Packard Vision Field Diagnostics.

9. Click Download.

NOTE: The download includes instructions on how to create a bootable CD or USB flash drive.
