Password Security
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.
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.
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. 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 the power cord.
2. Disconnect the keyboard, monitor, and any other external equipment.
3. Remove the access panel.
4. Locate, press, and hold the CMOS button in for five seconds.
5. Replace the access panel.
6. Reconnect the external devices.
7. Plug in the computer and turn on power.
Clearing or Disabling a Power-On or Setup password
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. The password jumper is green.
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. 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.

None required. Press any key or move the
mouse to wake the computer.
1. Ensure computer air vents not blocked
and processor cooling fan running.
2. Open hood, press power button, see if pro-
cessor fan spins. If not spinning, make sure
fan's cable plugged onto system board
header.
3. If fan plugged in, but not spinning,
replace heat sink/fan assembly.
1. Check if processor is present.
2. Reseat processor.
1. Open hood and ensure the 4 or 6-wire
power supply cable is seated into connector
on system board.
2. Check if a device is causing the problem
by removing ALL attached devices. Power
on system. If system enters the POST, then
power off and replace one device at a time
and repeat until failure occurs. Replace
device causing failure. Continue adding
devices one at a time to ensure all devices
functioning properly.
3. Replace the power supply.
4. Replace the system board.

1. Reseat DIMMs.
2. Make sure a DIMM is installed in black
DIMM connector first if only one DIMM.
3. Replace 3rd-party with HP memory.
4. Replace system board.
For systems with a graphics card:
1. Reseat graphics card.
2. Replace graphics card.
3. Replace system board.
For systems with integrated graphics,
replace system board.
Replace system board.
1. Reflash system ROM with latest BIOS
image.
2. Replace system board.
1. Check that voltage selector, located on the
rear of power supply (some models), is set to
appropriate voltage. Proper voltage setting
depends on region.
2. Unplug power cord from computer, wait
30 seconds, plug back in.
3. Replace system board.
4. Replace processor.
1. Check each option card by removing the
card (one at a time if multiple cards), then
power on system to see if fault goes away.
2. Once bad card identified, remove and
replace bad option card.
3. Replace system board.
1. Install a TXT capable processor.
2. Disable TXT in Computer Setup (F10)
utility.
3. Reinstall original processor.
Press and hold power button for less than 4
seconds. If hard drive LED turns green,
power button working correctly. Try the fol-
lowing:
1. Check that voltage selector (some mod-
els), located on the rear of power supply, is
set to appropriate voltage. Proper voltage
setting depends on region.
2. Replace system board.
OR
Press and hold power button for less than 4
seconds. If hard drive LED does not turn on
green then:
1. Check that unit plugged into a working
AC outlet.
2. Open hood and check that power button
harness is properly connected to system
board.
3. Check that both power supply cables are
properly connected to system board.
4. Check if 5V_aux light on system board is
turned on. If yes, replace power button har-
ness. If problem persists, replace system
board.
5. If 5V_aux light on system board is not
turned on, remove expansion cards one at a
time until 5V_aux light on system board
turns on. It problem persists, replace power
supply.
Recommended Action
1. Verify ROM, reflash if required
2. Remove suspected card, reboot
3. Clear CMOS memory
4. If message disappears, may be
problem with expansion card
5. Replace system board
1. Clear CMOS memory.
2. Remove expansion boards.
3. Replace system board.
1. Run Setup (F10).
2. Check DIMMs for proper seating,
type, and HP compatibility.
3. Remove DIMMs singularly and
reboot to isolate faulty DIMM.
4. Replace system board.
Rearrange DIMMs so that each channel
has the same amount of memory.
Check keyboard connection or keys.
Check connector for bent of missing
pins. Replace keyboard. If 304, possible
system board problem.
1. Reseat graphics card.
2. Clear CMOS.
3. Check monitor connection.
4. Replace graphics card.
1. Determine if hard drive is giving
correct error message. Enter
Computer Setup and run the Drive
Protection System test under Storage
> DPS Self-test.
2. Apply hard drive firmware patch if
applicable.
3. Back up contents and replace hard
drive.
Ensure SATA connectors are used in
ascending order. For one device, use
