Installing and Customizing the
Software
If your computer was not shipped with a Microsoft operating system, some portions of this
documentation do not apply. Additional information is available in online help after you install the
operating system.
NOTE: If the computer was shipped with Windows Vista or Windows 7 loaded, you will be prompted
to register the computer with HP Total Care before installing the operating system. You will see a
brief movie followed by an online registration form. Fill out the form, click the Begin button, and follow
the instructions on the screen.
CAUTION: Do not add optional hardware or third-party devices to the computer until the operating
system is successfully installed. Doing so may cause errors and prevent the operating system from
installing properly.
NOTE: Be sure there is a 10.2-cm (4-inch) clearance at the back of the unit and above the monitor
to permit the required airflow.
Installing the Operating System
The first time you turn on the computer, the operating system is installed automatically. This process
takes about 5 to 10 minutes, depending on which operating system is being installed. Carefully read
and follow the instructions on the screen to complete the installation.
CAUTION: Once the automatic installation has begun, DO NOT TURN OFF THE COMPUTER
UNTIL THE PROCESS IS COMPLETE. Turning off the computer during the installation process may
damage the software that runs the computer or prevent its proper installation.
NOTE: If the computer shipped with more than one operating system language on the hard drive,
the installation process could take up to 60 minutes.
If your computer was not shipped with a Microsoft operating system, some portions of this
documentation do not apply. Additional information is available in online help after you install the
operating system.

POST Delay (None, 5, 10 15, or 20 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.

PCI SERR# Generation.
●
PCI VGA Palette Snooping, which sets the VGA palette snooping bit in PCI configuration
space; only needed when more than one graphics controller is installed.
Allows you to set:
●
Num Lock State at Power-On (off/on). Default is on.
●
Hyper-threading (enable/disable). Default is enabled.
●
Internal Speaker (some models) (does not affect external speakers). Default is enabled.
●
NIC PXE Option ROM Download (enable/disable). 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 PXE option-ROM-enabled.
The Management Devices menu will only be displayed in the Advanced menu when the BIOS
detects multiple management options.
This option is for installed NIC cards that support ASF or DASH. Use the Management Devices
menu to select if the BIOS management operations will be through the embedded solution or one
of the installed NIC cards.

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.
SATA Hard Drives

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.
Hard Drive Capacities
The combination of the file system and the operating system used in the computer determines the
maximum usable size of a drive partition. A drive partition is the largest segment of a drive that may
be properly accessed by the operating system. A single hard drive may therefore be subdivided into a
number of unique drive partitions in order to make use of all of its space.
Because of the differences in the way that drive sizes are calculated, the size reported by the
operating system may differ from that marked on the hard drive or listed in the computer specification.
Drive size calculations by drive manufacturers are bytes to the base 10 while calculations by
Microsoft are bytes to the base 2.

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.
20
●
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.
Chapter 5 Identifying the Chassis, Routine Care, and Disassembly Preparation
●
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.

Operating Guidelines
To prevent overheating and to help prolong the life of the computer:
22
●
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 removed.
●
Do not place computers so near each other that they are subject to each other’s re-circulated or
preheated air.
●
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.

●
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 23 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 23.
When cleaning debris from under the keys, review all rules in General Cleaning Safety Precautions
on page 23 before following these procedures:
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.
Routine Care
23
●
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 23.
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 23.
Service Considerations
Listed below are some of the considerations that you should keep in mind during the disassembly and
assembly of the computer.
Tools and Software Requirements
To service the computer, you need the following:
●
Torx T-15 screwdriver (HP screwdriver with bits, PN 161946-001)
●
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: As each subassembly is removed from the computer, it should be placed away from the
work area to prevent damage.
24
Chapter 5 Identifying the Chassis, Routine Care, and Disassembly Preparation
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.
●
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 20
●
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.

Installing memory
Description
Spare part number
4-GB
646801-001
2-GB
646800-001
The memory modules are located under the rear cover on the right side of the computer (when
viewed from behind).
Figure 7-20 Memory location
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3SDRAM) small outline dual inline memory modules (SODIMMs).
DDR3-SDRAM SODIMMs
For proper system operation, the SODIMMs must be:
●
industry-standard 204-pin
●
unbuffered non-ECC PC3-10600 DDR3-1333 MHz-compliant
●
1.5 volt DDR3-SDRAM SODIMMs
The DDR3-SDRAM SODIMMs must also:
50
●
support CAS latency 9 DDR3 1333 MHz (9-9-9 timing)
●
contain the mandatory Joint Electronic Device Engineering Council (JEDEC) specification
Chapter 7 Removal and Replacement Procedures
In addition, the computer supports:
●
512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies
●
single-sided and double-sided SODIMMs
●
SODIMMs constructed with x8 and x16 devices; SODIMMs constructed with x4 SDRAM are not
supported
NOTE:
The system will not operate properly if you install unsupported SODIMMs.
Populating SODIMM sockets
The memory sockets on the system board can be populated with up to four industry-standard
SODIMMs. These memory sockets are populated with at least one preinstalled SODIMM. To achieve
the maximum memory support, you can populate the system board with up to 16 GB of memory.
There are four SODIMM 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 A. Sockets DIMM3 and DIMM4 operate in memory channel B.

NOTE: A SODIMM must occupy the black DIMM1 socket. Otherwise, the system will display
a POST error message indicating that a memory module is installed in the wrong socket
Installing memory
51
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the SODIMMs are installed.
●
The system will operate in single channel mode if the SODIMM 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 SODIMMs in Channel A is equal to the total memory capacity of the SODIMMs in Channel
B. The technology and device width can vary between the channels. For example, if Channel A
is populated with two 1 GB SODIMMs and Channel B is populated with one 2 GB SODIMM, the
system will operate in dual channel mode.
●
The system will operate in flex mode if the total memory capacity of the SODIMMs in Channel A
is not equal to the total memory capacity of the SODIMMs 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 SODIMM,
and three 1 GB SODIMMs, Channel A should be populated with the 2 GB SODIMM and one 1
GB SODIMM, and Channel B should be populated with the other two 1 GB SODIMMs. With this
configuration, 4 GB will run as dual channel and 1 GB will run as single channel.
Installing SODIMMS
When facing the rear of the computer, there are four memory sockets located behind the large access
panel on the right. You must remove this panel to remove or install memory.
CAUTION: Static electricity can damage the electronic components of the computer. 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.

POST Error Messages
This appendix lists the error codes, error messages, and the various indicator light and audible
sequences that you may encounter during Power-On Self-Test (POST) or computer restart, the
probable source of the problem, and steps you can take to resolve the error condition.
POST Message Disabled suppresses most system messages during POST, such as memory count
and non-error text messages. If a POST error occurs, the screen will display the error message. To
manually switch to the POST Messages Enabled mode during POST, press any key (except F10,
F11, or F12). The default mode is POST Message Disabled.
The speed at which the computer loads the operating system and the extent to which it is tested are
determined by the POST mode selection.
Quick Boot is a fast startup process that does not run all of the system level tests, such as the
memory test. Full Boot runs all of the ROM-based system tests and takes longer to complete.
Full Boot may also be enabled to run every 1 to 30 days on a regularly scheduled basis. To establish
the schedule, reconfigure the computer to the Full Boot Every x Days mode, using Computer Setup.

Solving Memory Problems
If you encounter memory problems, some common causes and solutions are listed in the following
table.
CAUTION: Power may still be supplied to the DIMMs when the computer is turned off (depending
on the Management Engine (ME) settings). To avoid damage to the DIMMs or the system board, you
must unplug the computer power cord before attempting to reseat, install, or remove a DIMM module.
For those systems that support ECC memory, HP does not support mixing ECC and non-ECC
memory. Otherwise, the computer will not boot the operating system.

XMM1 socket on the system board. This socket must be
populated with a memory module.
Memory module is not the correct type or speed grade for
the system or the new memory module is not seated
properly.
Replace module with the correct industry-standard device for
the computer. On some models, ECC and non-ECC memory
modules cannot be mixed.
