Description

Device Configuration

Lists all installed BIOS-controlled storage devices.
When a device is selected, detailed information and options are displayed. The following options
may be presented:
●

Hard Disk: Size, model, firmware version, serial number, connector color.
Translation mode (ATA disks only)
Lets you select the translation mode to be used for the device. This enables the BIOS to
access disks partitioned and formatted on other systems and may be necessary for users of
older versions of UNIX (e.g., SCO UNIX version 3.2). Options are Automatic, Bit-Shift,
LBA Assisted, User, and Off.
Available only when the drive translation mode is set to User, allows you to specify the
parameters (logical cylinders, heads, and sectors per track) used by the BIOS to translate
disk I/O requests (from the operating system or an application) into terms the hard drive can
accept. Logical cylinders may not exceed 1024. The number of heads may not exceed 256.
The number of sectors per track may not exceed 63.
CAUTION: Ordinarily, the translation mode selected automatically by the BIOS should not
be changed. If the selected translation mode is not compatible with the translation mode that
was active when the disk was partitioned and formatted, the data on the disk will be
inaccessible.

●

CD-ROM: Model, firmware version, serial number, connector color (not included for USB CDROM).

●

SSD Life Used
NOTE: Displays for solid-state drives.

●

SMART (ATA disks only)

●

Diskette: Model and firmware version.

NOTE: Displays for USB diskette drives.

Table 3-3 Computer Setup—Storage (continued)
Storage Options

eSATA Port
Allows you to set a SATA port as an eSATA port for use with an external drive. Default is enabled.
This setting affects only the port with the black connector, labeled as eSATA on the system board.
This port should have the eSATA back panel connector attached to use eSATA drives. For more
information, see the eSATA white paper at www.hp.com.
SATA Emulation
Allows you to choose how the SATA controller and devices are accessed by the operating
system. There are three supported options: IDE, RAID, 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.
RAID - Allows DOS and boot access to RAID volumes. Use this mode with the RAID device driver
loaded in the operating system to take advantage of RAID features.
AHCI (default option) - Allows operating systems with AHCI device drivers loaded to take
advantage of more advanced features of the SATA controller.
NOTE: The RAID/AHCI device driver must be installed prior to attempting to boot from a RAID/
AHCI volume. If you attempt to boot from a RAID/AHCI volume without the required device driver
installed, the system will crash (blue screen). RAID volumes may become corrupted if they are
booted to after disabling RAID.
Removable Media Boot
Enables/disables ability to boot the system from removable media. Default is enabled.
Max eSATA Speed
Allows you to choose 1.5 Gbps or 3.0 Gpbs as the maximum eSATA speed. By default, the speed
is limited to 1.5 Gbps for maximum reliability.
CAUTION: Consult your eSATA drive and cable manufacturer before enabling 3.0 Gpbs speed.
Some drive and cable combinations may not run reliably at 3.0 Gpbs.

DPS Self-Test

Allows you to execute self-tests on ATA hard drives capable of performing the Drive Protection
System (DPS) self-tests.
NOTE: This selection will only appear when at least one drive capable of performing the DPS
self-tests is attached to the system.

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.

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

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.

●

Different activities generate different amounts of static electricity.

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.

Electrostatic Discharge Information

25

●

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 them on
both feet with a maximum of one-megohm ± 10% resistance between the operator and ground.

●

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.

●

Keep work area free of nonconductive materials such as ordinary plastic assembly aids and
Styrofoam.

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.

Operating Guidelines

27

●

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

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 28 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 28.
When cleaning debris from under the keys, review all rules in General Cleaning Safety Precautions
on page 28 before following these procedures:

Chapter 5 Identifying the Chassis, Routine Care, and Disassembly Preparation

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 28.

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 28.

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.

Service Considerations

29

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

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

●

Torx T-15 screwdriver with small diameter shank (for certain front bezel removal)

●

Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver)

●

Phillips #2 screwdriver

●

Diagnostics software

●

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

30

●

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.

●

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.

Chapter 5 Identifying the Chassis, Routine Care, and Disassembly Preparation

●

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 25

●

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.
See the appropriate removal and replacement chapter for the chassis you are working on in this
guide for instructions on the replacement procedures.
WARNING! This computer contains a lithium battery. There is a risk of fire and chemical burn if the
battery is handled improperly. Do not disassemble, crush, puncture, short external contacts, dispose
in water or fire, or expose it to temperatures higher than 140ºF (60ºC). Do not attempt to recharge the
battery.
NOTE: Batteries, battery packs, and accumulators should not be disposed of together with the
general household waste. In order to forward them to recycling or proper disposal, please use the
public collection system or return them to HP, their authorized partners, or their agents.

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:

54

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

Chapter 7 Removal and Replacement Procedures Small Form Factor (SFF) Chassis

Populating DIMM Sockets
There are two DIMM sockets on the system board: XMM1 and XMM3 with one socket per Channel.
XMM3 operates in memory channel A. XMM1 operates in memory Channel B.
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 DIMM in Channel A is equal to the total memory capacity of the DIMM in Channel B.

●

The system will operate in flex mode if the total memory capacity of the DIMM in Channel A is
not equal to the total memory capacity of the DIMM 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. If one channel will have more
memory than the other, the larger amount should be assigned to Channel A.

●

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.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.

Cable Management
The Small Form Factor chassis is a very compact computer and proper routing of the internal cables
is critical to the operation of the computer. 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 movable or rotating parts like the power supply and drive cage to prevent
them from being cut or crimped when the component is lowered into its normal position.

●

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.

When removing the power supply power cables from the connector on the system board, always
follow these steps:
1.

Squeeze on the top of the retaining latch attached to the cable end of the connector (1).

2.

Grasp the cable end of the connector and pull it straight up (2).
CAUTION: Always pull the connector - NEVER pull on the cable. Pulling on the cable could
damage the cable and result in a failed power supply.

HP PC Hardware Diagnostics

Use the UEFI-based hardware diagnostic solution that HP includes on all products to diagnose
hardware issues. You can use this tool even if the computer will not boot to the operating system.
This tool also works with components not diagnosed in HPSA.

Why run HP PC Hardware Diagnostics
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.

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 the Computer Setup (F10) Utility Guide for information on
backing up the CMOS settings.

needed later. Back up is easily done through Computer Setup.

4.

Locate, press, and hold the CMOS button in for five seconds.
NOTE: Make sure you have disconnected the AC power cord from the wall outlet. The CMOS
button will not clear CMOS if the power cord is connected.

Drive Protection System (DPS)

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.
When these systems are built, each installed hard drive is tested using DPS, and a permanent record
of key information is written onto the drive. Each time DPS is run, test results are written to the hard
drive. Your service provider can use this information to help diagnose conditions that caused you to
run the DPS software.
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.

163

Accessing DPS Through Computer Setup
When the computer does not power on properly you should use Computer Setup to access the DPS
program. To access DPS, perform the following steps:
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
key.
NOTE: If you do not press the F10 key while the message is displayed, you must turn the
computer off, then on again, to access the utility.
A choice of five headings appears in the Computer Setup Utilities menu: File, Storage,
Security, Power, and Advanced.

3.

Select Storage > DPS Self-Test.
The screen will display the list of DPS-capable hard drives that are installed on the computer.
NOTE: If no DPS-capable hard drives are installed, the DPS Self-Test option will not appear
on the screen.

4.

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

When the test has been completed, one of three messages will be displayed:
●

Test Succeeded. Completion Code 0.

●

Test Aborted. Completion Code 1 or 2.

●

Test Failed. Drive Replacement Recommended. Completion Code 3 through 14.

If the test failed, the completion code should be recorded and reported to your service provider for
help in diagnosing the computer problem.
