Storage Options

SATA Emulation
Allows you to choose how the SATA controller and devices are accessed by the operating system.
There are two supported options: IDE and AHCI (default).
CAUTION: SATA emulation changes may prevent access to existing hard drive data and
degrade or corrupt established volumes.
IDE - This is the most backwards-compatible setting of the three options. Operating systems usually
do not require additional driver support in IDE mode.
AHCI (default option) - Allows operating systems with AHCI device drivers loaded to take
advantage of more advanced features of the SATA controller.
NOTE: The AHCI device driver must be installed prior to attempting to boot from a AHCI volume.
If you attempt to boot from a AHCI volume without the required device driver installed, the system
will crash (blue screen).
Removable Media Boot
Enables/disables ability to boot the system from removable media. Default is enabled.

Boot Order

Allows you to:
●

EFI Boot Sources: Specify the order in which EFI boot sources (such as a internal hard drive,
USB hard drive, USB optical drive, or internal optical drive) are checked for a bootable
operating system image. Each device on the list may be individually excluded from or included
for consideration as a bootable operating system source.
EFI boot sources always have precedence over legacy boot sources.

Legacy Boot Sources: Specify the order in which legacy boot sources (such as a network
interface card, internal hard drive, USB optical drive, or internal optical drive) are checked for
a bootable operating system image. Each device on the list may be individually excluded from
or included for consideration as a bootable operating system source.
Specify the order of attached hard drives. The first hard drive in the order will have priority in
the boot sequence and will be recognized as drive C (if any devices are attached).

NOTE: To drag a device to a preferred place, press Enter. To remove the device from
consideration as a bootable device, press F5.
You can use F5 to disable individual boot items, as well as disable EFI boot and/or legacy boot.
NOTE: MS-DOS drive lettering assignments may not apply after a non-MS-DOS operating system
has started.
Shortcut to Temporarily Override Boot Order
To boot one time from a device other than the default device specified in Boot Order, restart the
computer and press Esc (to access the boot menu) and then F9 (Boot Order), or only F9 (skipping
the boot menu) when the monitor light turns green. After POST is completed, a list of bootable
devices is displayed. Use the arrow keys to select the preferred bootable device and press Enter.
The computer then boots from the selected non-default device for this one time.

Chapter 3 Computer Setup (F10) Utility

Table 3-4 Computer Setup—Security (continued)
Master Boot Record
Security

Enables/disables Master Boot Record (MBR) security.
The MBR contains information needed to successfully boot from a disk and to access the data stored
on the disk. Master Boot Record Security may prevent unintentional or malicious changes to the
MBR, such as those caused by some viruses or by the incorrect use of certain disk utilities. It also
allows you to recover the "last known good" MBR, should changes to the MBR be detected when
the system is restarted.
When MBR Security is enabled, the BIOS prevents any changes being made to the MBR of the
current bootable disk while in MS-DOS or Windows Safe Mode.
NOTE: Most operating systems control access to the MBR of the current bootable disk; the BIOS
cannot prevent changes that may occur while the operating system is running.
Restores the backup Master Boot Record to the current bootable disk. Default is disabled.
Only appears if all of the following conditions are true:
●

MBR security is enabled

●

A backup copy of the MBR has been previously saved

●

The current bootable disk is the same disk from which the backup copy was saved

CAUTION: Restoring a previously saved MBR after a disk utility or operating system has modified
the MBR, may cause the data on the disk to become inaccessible. Only restore a previously saved
MBR if you are confident that the current bootable disk's MBR has been corrupted or infected with a
virus.

◦

FullBoot Every x Days = Memory count on 1st cold boot on or after the xth day. No more
memory counts until 1st cold boot on or after x days. Clears memory on all boots.

●

POST messages (enable/disable). Enabling this feature will cause the system to display POST
error messages, which are error messages displayed on the monitor during the Power On Self
Test if the BIOS encounters some kind of problem while starting the PC. A POST error message
will only display on screen if the computer is capable of booting this far. If the POST detects
an error before this point, a beep code is generated instead. Default is disabled.

●

Press the ESC key for Startup Menu (Enable/Disable). This feature controls the display of the
text “Press the ESC key for Startup Menu” during POST. This text does not display on
Windows 8 systems with Fast Boot support. Other text also will not display (for example,
Ownership Tag). Default is enabled.

●

Option ROM Prompt (enable/disable). Enabling this feature will cause the system to display a
message before loading option ROMs. Default is enabled.

●

After Power Loss (off/on/previous state). Default is Power off. Setting this option to:
◦

Power off—causes the computer to remain powered off when power is restored.

◦

Power on—causes the computer to power on automatically as soon as power is restored.

restored, if it was on when power was lost.

NOTE: If you turn off power to the computer using the switch on a power strip, you will not be
able to use the suspend/sleep feature or the Remote Management features.
●

POST Delay (in seconds). Enabling this feature will add a user-specified delay to the POST
process. This delay is sometimes needed for hard disks on some PCI cards that spin up very
slowly, so slowly that they are not ready to boot by the time POST is finished. The POST delay
also gives you more time to select F10 to enter Computer (F10) Setup. Default is None.

●

Remote Wakeup Boot Source (remote server/local hard drive). Default is Local hard drive.

●

Factory Recovery Boot Support (Enable/Disable). Provides the ability for the BIOS to redirect
the boot to the recovery partition on the user hard drive, if present. Some versions of the
recovery software honor the F11 key press even when this feature is disabled by the BIOS.
Default is disabled.

graphics memory allocation. The value you choose is allocated permanently to graphics and is
unavailable to the operating system. For example, if you set this value to 512M on a system
with 2 GB of RAM, the system always allocates 512 MB for graphics and the other 1.5 GB for
use by the BIOS and operating system. Default is Auto which sets memory allocation to 512
MB.
If you select Force, the UMA Frame Buffer Size option displays, which lets you set the UMA
memory size allocation between 32 MB and 1 GB.

●

Internal Speaker (does not affect external speakers). Default is enabled.

●

NIC PXE Option ROM Download (PXE, iSCSI, disabled). The BIOS contains an embedded
NIC option ROM to allow the unit to boot through the network to a PXE server. This is typically
used to download a corporate image to a hard drive. The NIC option ROM takes up memory
space below 1MB commonly referred to as DOS Compatibility Hole (DCH) space. This space
is limited. This F10 option will allow users to disable the downloading of this embedded NIC
option ROM thus giving more DCH space for additional PCI cards which may need option
ROM space. The default will be to have the NIC option-ROM-enabled. Default is PXE.

●

Multi-Processor (enable/disable). Use this option to disable multi-processor support under the
OS. Default is enabled.

●

Hyper threading (enable/disable). Use this option to disable processor hyper-threading.

●

Management Engine is set to a temporarily disabled state and will not provide functions
beyond necessary system configuration. Default is enabled.

●

Unconfigure AMT/ME (enable/disable). Allows you to unconfigure any provisioned
management settings for AMT. The AMT settings are restored to factory defaults. This feature
should be used with caution as AMT will not be able to provide any set AMT management
functions once unconfigured. Default is disabled.

●

Hide Unconfigure ME Confirmation Prompt (enable/disable). Allows you to set the system to
not display the confirmation to unconfigure ME.

●

Watchdog Timer (enable/disable). Allows you to set amount of time for a operating system
and BIOS watchdog alert to be sent if the timers are not deactivated. BIOS watchdog is
deactivated by BIOS and would indicate that a halt occurred during execution if the alert is
sent to the management console. An operating system alert is deactivated by the operating
system image and would indicate that a hang occurred during its initialization. Default is
enabled.

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. (See Computer Setup—File
on page 12 in the Computer Setup—File table.)
NOTE: It is recommended that you save any modified computer configuration settings to a USB flash
media device and save the device for possible future use.
To restore the configuration, insert the USB flash media device with the saved configuration and
perform the Restore from Removable Media command with the Computer Setup (F10) Utility.
(See Computer Setup—File on page 12 in the Computer Setup—File table.)

Routine Care, SATA Drive
Guidelines, and Disassembly
Preparation

This chapter provides general service information for the computer. Adherence to the procedures and
precautions described in this chapter is essential for proper service.
CAUTION: When the computer is plugged into an AC power source, voltage is always applied to
the system board. You must disconnect the power cord from the power source before opening the
computer to prevent system board or component damage.

Electrostatic Discharge Information
A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive
devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic
device exposed to electrostatic discharge (ESD) may not appear to be affected at all and can work
perfectly throughout a normal cycle. The device may function normally for a while, but it has been
degraded in the internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the discharge
contains enough power to alter device parameters or melt silicon junctions.

Generating Static
The following table shows that:
●

Different activities generate different amounts of static electricity.

●

Static electricity increases as humidity decreases.

Preventing Electrostatic Damage to Equipment
Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree
of sensitivity. The following packaging and grounding precautions are necessary to prevent damage to
electric components and accessories.
●

To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes.

●

Protect all electrostatic parts and assemblies with conductive or approved containers or
packaging.

●

Keep electrostatic sensitive parts in their containers until they arrive at static-free stations.

●

Place items on a grounded surface before removing them from their container.

●

Always be properly grounded when touching a sensitive component or assembly.

●

Avoid contact with pins, leads, or circuitry.

●

Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive
foam.

Personal Grounding Methods and Equipment
Use the following equipment to prevent static electricity damage to equipment:

●

Wrist straps are flexible straps with a maximum of one-megohm ± 10% resistance in the ground
cords. To provide proper ground, a strap must be worn snug against bare skin. The ground cord
must be connected and fit snugly into the banana plug connector on the grounding mat or
workstation.

●

Heel straps/Toe straps/Boot straps can be used at standing workstations and are
compatible with most types of shoes or boots. On conductive floors or dissipative floor mats, use

●

Cover the work surface with approved static-dissipative material. Provide a wrist strap connected
to the work surface and properly grounded tools and equipment.

●

Use static-dissipative mats, foot straps, or air ionizers to give added protection.

●

Handle electrostatic sensitive components, parts, and assemblies by the case or PCB laminate.
Handle them only at static-free work areas.

●

Turn off power and input signals before inserting and removing connectors or test equipment.

●

Use fixtures made of static-safe materials when fixtures must directly contact dissipative surfaces.

●

Operating Guidelines
To prevent overheating and to help prolong the life of the computer:

●

Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold.

●

Operate the computer on a sturdy, level surface. Leave a 10.2-cm (4-inch) clearance on all vented
sides of the computer and above the monitor to permit the required airflow.

●

Never restrict the airflow into the computer by blocking any vents or air intakes. Do not place the
keyboard, with the keyboard feet down, directly against the front of the desktop unit as this also
restricts airflow.

●

Occasionally clean the air vents on all vented sides of the computer. Lint, dust, and other foreign
matter can block the vents and limit the airflow. Be sure to unplug the computer before cleaning
the air vents.

●

Never operate the computer with the cover or side panel removed.

●

Do not stack computers on top of each other or place computers so near each other that they are
subject to each other’s re-circulated or preheated air.

●

If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must
be provided on the enclosure, and the same operating guidelines listed above will still apply.

●

Keep liquids away from the computer and keyboard.

●

Never cover the ventilation slots on the monitor with any type of material.

●

Install or enable power management functions of the operating system or other software, including
sleep states.

Routine Care
General Cleaning Safety Precautions
1.

Never use solvents or flammable solutions to clean the computer.

Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and
then use the cloth on the component.

Always unplug the computer when cleaning with liquids or damp cloths.

Always unplug the computer before cleaning the keyboard, mouse, or air vents.

Disconnect the keyboard before cleaning it.

Wear safety glasses equipped with side shields when cleaning the keyboard.

Cleaning the Computer Case
Follow all safety precautions in General Cleaning Safety Precautions on page 51 before cleaning the
computer.
To clean the computer case, follow the procedures described below:
●

To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.

●

For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping it with
a cloth or swab dampened with clear water.

●

For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed as the alcohol will
evaporate quickly and not leave a residue.

●

After cleaning, always wipe the unit with a clean, lint-free cloth.

●

Occasionally clean the air vents on the computer. Lint and other foreign matter can block the vents
and limit the airflow.

Cleaning the Keyboard
Follow all safety precautions in General Cleaning Safety Precautions on page 51 before cleaning the
keyboard.
To clean the tops of the keys or the keyboard body, follow the procedures described in Cleaning the
Computer Case on page 51.
When cleaning debris from under the keys, review all rules in General Cleaning Safety Precautions
on page 51 before following these procedures:

Routine Care

CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from
under the keys.
●

Visible debris underneath or between the keys may be removed by vacuuming or shaking.

●

Canned, pressurized air may be used to clean debris from under the keys. Caution should be used
as too much air pressure can dislodge lubricants applied under the wide keys.

●

If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool
is available through many electronic supply outlets.
CAUTION: Never remove a wide leveled key (like the space bar) from the keyboard. If these
keys are improperly removed or installed, the keyboard may not function properly.

●

Cleaning under a key may be done with a swab moistened with isopropyl alcohol and squeezed
out. Be careful not to wipe away lubricants necessary for proper key functions. Use tweezers to
remove any fibers or dirt in confined areas. Allow the parts to air dry before reassembly.

Cleaning the Monitor
●

Wipe the monitor screen with a clean cloth moistened with water or with a towelette designed for
cleaning monitors. Do not use sprays or aerosols directly on the screen; the liquid may seep into
the housing and damage a component. Never use solvents or flammable liquids on the monitor.

●

To clean the monitor body follow the procedures in Cleaning the Computer Case on page 51.

Cleaning the Mouse
Before cleaning the mouse, ensure that the power to the computer is turned off.
●

Clean the mouse ball by first removing the retaining plate and the ball from the housing. Pull out
any debris from the ball socket and wipe the ball with a clean, dry cloth before reassembly.

●

To clean the mouse body, follow the procedures in Cleaning the Computer Case on page 51.

Service Considerations
Listed below are some of the considerations that you should keep in mind during the disassembly and
assembly of the computer.

Power Supply Fan
The power supply fan is a variable-speed fan based on the temperature in the power supply.
CAUTION: The cooling fan is always on when the computer is in the “On” mode. The cooling fan is
off when the computer is in “Standby,” “Suspend,” or “Off” modes.
You must disconnect the power cord from the power source before opening the computer to prevent
system board or component damage.

Chapter 5 Routine Care, SATA Drive Guidelines, and Disassembly Preparation

Tools and Software Requirements
To service the computer, you need the following:
●

Torx T-15 screwdriver (HP screwdriver with bits, PN 161946-001)

●

HP tamper-resistant T-15 wrench (Smart Cover FailSafe Key, PN 166527-001) or HP tamperresistant bits (Smart Cover FailSafe Key, PN 166527-002)

Screws
The screws used in the computer are not interchangeable. They may have standard or metric threads
and may be of different lengths. If an incorrect screw is used during the reassembly process, it can
damage the unit. HP strongly recommends that all screws removed during disassembly be kept with the
part that was removed, then returned to their proper locations.
CAUTION:
drives only.

Metric screws have a black finish. U.S. screws have a silver finish and are used on hard

CAUTION: As each subassembly is removed from the computer, it should be placed away from the
work area to prevent damage.

Cables and Connectors
Most cables used throughout the unit are flat, flexible cables. These cables must be handled with care
to avoid damage. Apply only the tension required to seat or unseat the cables during insertion or
removal from the connector. Handle cables by the connector whenever possible. In all cases, avoid
bending or twisting the cables, and ensure that the cables are routed in such a way that they cannot be
caught or snagged by parts being removed or replaced.
CAUTION: When servicing this computer, ensure that cables are placed in their proper location
during the reassembly process. Improper cable placement can damage the computer.

Hard Drives
Handle hard drives as delicate, precision components, avoiding all physical shock and vibration. This
applies to failed drives as well as replacement spares.
●

If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective
packaging and label the package “Fragile: Handle With Care.”

●

Do not remove hard drives from the shipping package for storage. Keep hard drives in their
protective packaging until they are actually mounted in the CPU.

●

Avoid dropping drives from any height onto any surface.

Service Considerations

●

If you are inserting or removing a hard drive, turn off the computer. Do not remove a hard drive
while the computer is on or in standby mode.

●

Before handling a drive, ensure that you are discharged of static electricity. While handling a
drive, avoid touching the connector. For more information about preventing electrostatic damage,
refer to Electrostatic Discharge Information on page 47

●

Do not use excessive force when inserting a drive.

●

Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic
fields such as monitors or speakers.

Lithium Coin Cell Battery
The battery that comes with the computer provides power to the real-time clock and has a minimum
lifetime of about three years.

SATA Hard Drive Cables
SATA Data Cable
Always use an HP approved SATA 3.0 Gb/s cable as it is fully backwards compatible with the SATA
1.5 Gb/s drives.
Current HP desktop products ship with SATA 3.0 Gb/s hard drives.
SATA data cables are susceptible to damage if overflexed. Never crease a SATA data cable and never
bend it tighter than a 30 mm (1.18 in) radius.
The SATA data cable is a thin, 7-pin cable designed to transmit data for only a single drive.

SMART ATA Drives
The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for the HP Personal
Computers have built-in drive failure prediction that warns the user or network administrator of an
impending failure or crash of the hard drive. The SMART drive tracks fault prediction and failure
indication parameters such as reallocated sector count, spin retry count, and calibration retry count. If
the drive determines that a failure is imminent, it generates a fault alert.

Cable Management
Always follow good cable management practices when working inside the computer.
●

Keep cables away from major heat sources like the heat sink.

●

Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these
are not designed to take excessive pressure on them.

●

Keep cables clear of sliding or moveable parts to prevent them from being cut or crimped when
the parts are moved.

●

When folding a flat ribbon cable, never fold to a sharp crease. Sharp creases may damage the
wires.

●

Some flat ribbon cables come prefolded. Never change the folds on these cables.

●

Do not bend any cable sharply. A sharp bend can break the internal wires.

●

Never bend a SATA data cable tighter than a 30 mm (1.18 in) radius.

●

Never crease a SATA data cable.

●

Do not rely on components like the drive cage, power supply, or computer cover to push cables
down into the chassis. Always position the cables to lay properly by themselves.

2-GB, PC3-12800

671612-001

The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3SDRAM) dual inline memory modules (DIMMs).

DIMMs
The memory sockets on the system board can be populated with up to four industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to 16-GB of memory configured in a highperforming dual channel mode.

DDR3-SDRAM DIMMs
CAUTION: This product DOES NOT support DDR3 Ultra Low Voltage (DDR3U) memory. The
processor is not compatible with DDR3U memory and if you plug DDR3U memory into the system
board, it can cause the physical damage to the DIMM or invoke system malfunction.
For proper system operation, the DDR3-SDRAM DIMMs must be:
●

industry-standard 240-pin

●

unbuffered non-ECC PC3-12800 DDR3-1600 MHz-compliant

●

1.5 volt DDR3-SDRAM DIMMs

The DDR3-SDRAM DIMMs must also:
●

support CAS latency 11 DDR3 1600 MHz (11-11-11 timing)

●

contain the mandatory JEDEC SPD information

In addition, the computer supports:
●

512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies

●

single-sided and double-sided DIMMs

●

DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not
supported

NOTE: The system will not operate properly if you install unsupported DIMMs.

Chapter 6 Removal and Replacement Procedures Microtower (MT) Chassis

Populating DIMM Sockets
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are
labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory
channel B. Sockets DIMM3 and DIMM4 operate in memory channel A.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.
●

The system will operate in single channel mode if the DIMM sockets are populated in one channel
only.

●

The system will operate in a higher-performing dual channel mode if the total memory capacity of
the DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B. The
technology and device width can vary between the channels. For example, if Channel A is
populated with two 1-GB DIMMs and Channel B is populated with one 2-GB DIMM, the system
will operate in dual channel mode.

●

The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is
not equal to the total memory capacity of the DIMMs in Channel B. In flex mode, the channel
populated with the least amount of memory describes the total amount of memory assigned to dual
channel and the remainder is assigned to single channel. For optimal speed, the channels should
be balanced so that the largest amount of memory is spread between the two channels. If one
channel will have more memory than the other, the larger amount should be assigned to Channel
A. For example, if you are populating the sockets with one 2-GB DIMM, and three 1-GB DIMMs,
Channel A should be populated with the 2-GB DIMM and one 1-GB DIMM, and Channel B should
be populated with the other two 1-GB DIMMs. With this configuration, 4-GB will run as dual
channel and 1-GB will run as single channel.

●

In any mode, the maximum operational speed is determined by the slowest DIMM in the system.

Installing DIMMs
CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power
to drain before adding or removing memory modules. Regardless of the power-on state, voltage is
always supplied to the memory modules as long as the computer is plugged into an active AC outlet.
Adding or removing memory modules while voltage is present may cause irreparable damage to the
memory modules or system board.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is
important to use memory modules with gold-plated metal contacts to prevent corrosion and/or
oxidation resulting from having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before
beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object. For more information, refer to Electrostatic Discharge Information on page 47.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.
1.

Prepare the computer for disassembly (Preparation for Disassembly on page 56)

Remove the access panel (Computer Access Panel on page 57)

Memory

Open both latches of the memory module socket (1), and insert the memory module into the
socket (2).
Figure 6-6 Installing a DIMM

NOTE: A memory module can be installed in only one way. Match the notch on the module with
the tab on the memory socket.
Populate the black DIMM sockets before the white DIMM sockets.
For maximum performance, populate the sockets so that the memory capacity is spread as equally
as possible between Channel A and Channel B. Refer to Populating DIMM Sockets on page 63
for more information.
4.

Push the module down into the socket, ensuring that the module is fully inserted and properly
seated. Make sure the latches are in the closed position (3).

Repeat steps 3 and 4 to install any additional modules.

Replace the computer access panel.

Reconnect the power cord and turn on the computer.

Lock any security devices that were disengaged when the access panel was removed.

The computer should automatically recognize the additional memory the next time you turn on the
computer.

10 Password Security and Resetting
CMOS

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. It is important to
back up the computer CMOS settings before resetting them in case they are needed later. Back up is
easily done through Computer Setup. See Computer Setup (F10) Utility on page 10 for information on
backing up the CMOS settings.

195

Resetting the Password Jumper
CAUTION: If you enable the stringent security feature in Computer Setup and you forget the setup
password or the power-on password, the computer is inaccessible and can no longer be used.
Enabling the stringent password disables the ability to reset the password by moving the jumper on the
system board.
If you lose or forget the password, the system board must be replaced. This scenario is not covered
under warranty.
To prevent the computer from becoming permanently unusable, record your configured setup password
or power-on password in a safe place away from your computer. Without these passwords, the
computer cannot be unlocked.
To disable the power-on or setup password features, or to clear the power-on or setup 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 from the power outlet.

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.

Remove the computer cover or access panel.

Locate the header and jumper.
NOTE: The password jumper is green 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.

196

Remove the jumper from pins 1 and 2. Place the jumper on either pin 1 or 2, but not both, so that
it does not get lost.

Replace the computer cover or access panel.

Reconnect the external equipment.

Chapter 10 Password Security and Resetting CMOS

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

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.

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.

11 HP PC Hardware Diagnostics

To help troubleshoot and diagnose failures, use the UEFI-based hardware diagnostic solution that HP
includes on all products. This tool can even be used if the computer will not boot to the operating
system.

Why run HP PC Hardware Diagnostics – UEFI
The HP PC Hardware Diagnostic tools simplify the process of diagnosing hardware issues and expedite
the support process when issues are found. The tools save time by pinpointing the component that
needs to be replaced.
●

Isolate true hardware failures: The diagnostics run outside of the operating system so they
effectively isolate hardware failures from issues that may be caused by the operating system or
other software components.

●

Failure ID: When a failure is detected that requires hardware replacement, a 24-digit Failure ID
is generated. This ID can then be provided to the call agent, who will either schedule support or
provide replacement parts.

How to access and run HP PC Hardware Diagnostics
- UEFI
To access the UEFI diagnostics:
1.

Restart or turn on the computer and press Esc repeatedly until the BIOS boot menu appears.

Press F2 or select Diagnostics (F2).
