1 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.

Installing the Operating System

1

Downloading Microsoft Windows Updates

1. To set up your Internet connection, click Start > Internet Explorer and follow the instructions on

the screen.

2. Once an Internet connection has been established, click the Start button.

3. Select the All Programs menu.

4. Click on the Windows Update link.

In Windows Vista and Windows 7, the Windows Update screen appears. Click view available
updates and make sure all critical updates are selected. Click the Install button and follow the

instructions on the screen.

In Windows XP, you will be directed to the Microsoft Windows Update Web site. If you see
one or more pop-up windows that ask you to install a program from

http://www.microsoft.com,

click Yes to install the program. Follow the instructions on the Microsoft Web site to scan for
updates and install critical updates and service packs.

It is recommended that you install all of the critical updates and service packs.

5. After the updates have been installed, Windows will prompt you to reboot the machine. Be sure

to save any files or documents that you may have open before rebooting. Then select Yes to
reboot the machine.

Installing or Upgrading Device Drivers (Windows
systems)

When installing optional hardware devices after the operating system installation is complete, you
must also install the drivers for each of the devices.

If prompted for the i386 directory, replace the path specification with C:\i386, or use the Browse
button in the dialog box to locate the i386 folder. This action points the operating system to the
appropriate drivers.

Obtain the latest support software, including support software for the operating system from

http://www.hp.com/support. Select your country and language, select Download drivers and

software (and firmware), enter the model number of the computer, and press Enter.

Accessing Disk Image (ISO) Files

There are disk image files (ISO files) included on your PC that contain the installation software for
additional software. These CD image files are located in the folder C:\SWSetup\ISOs. Each .iso file
can be burned to CD media to create an installation CD. It is recommended that these disks be
created and the software installed in order to get the most from your PC. The software and image file
names are:

●

Corel WinDVD SD and BD – installation software for WinDVD – used to play DVD movies

●

HP Insight Diagnostics OR Vision Diagnostics – software to perform diagnostic activities on your
PC

2 Chapter 1 Installing and Customizing the Software

Protecting the Software

To protect the software from loss or damage, keep a backup copy of all system software,
applications, and related files stored on the hard drive. Refer to the operating system or backup utility
documentation for instructions on making backup copies of your data files.

3 Serial ATA (SATA) Drive Guidelines

and Features

NOTE: HP only supports the use of SATA hard drives on these models of computer. No Parallel

ATA (PATA) drives are supported.

SATA Hard Drives

Serial ATA Hard Drive Characteristics

Number of pins/conductors in data cable 7/7

Number of pins in power cable 15

Maximum data cable length 39.37 in (100 cm)

Data interface voltage differential 400-700 mV

Drive voltages 3.3 V, 5 V, 12 V

Jumpers for configuring drive N/A

Data transfer rate 3.0 Gb/s

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.

20 Chapter 3 Serial ATA (SATA) Drive Guidelines and Features

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 static­sensitive 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.

Electrostatic Discharge Information

25

●

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 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:

●

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.

Operating Guidelines

27

●

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

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.

28 Chapter 4 Identifying the Chassis, Routine Care, and Disassembly Preparation

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:

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.

Service Considerations

29

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.

Tools and Software Requirements

To service the computer, you need the following:

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.

30 Chapter 4 Identifying the Chassis, Routine Care, and Disassembly Preparation

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 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.

6 Removal and Replacement Procedures

Microtower (MT) Chassis

Adherence to the procedures and precautions described in this chapter is essential for proper service.
After completing all necessary removal and replacement procedures, run the Diagnostics utility to
verify that all components operate properly.

NOTE: Not all features listed in this guide are available on all computers.

Preparation for Disassembly

1. Close any open software applications.

2. Exit the operating system.

3. Remove any diskette or compact disc from the computer.

4. Turn off the computer and any peripheral devices that are connected to it.

CAUTION: Turn off the computer before disconnecting any cables.

CAUTION: Regardless of the power-on state, voltage is always present on the system board

as long as the system is plugged into an active AC outlet. In some systems the cooling fan is on

even when the computer is in the “Standby,” or “Suspend” modes. The power cord should

always be disconnected before servicing a unit.

5. Disconnect the power cord from the electrical outlet and then from the computer.

6. Disconnect all peripheral device cables from the computer.

NOTE: During disassembly, label each cable as you remove it, noting its position and routing.

Memory

Description Spare part number

2-GB memory module (PC3-10600, 1333-MHz) 626898-001

1-GB memory module (PC3-10600, 1333-MHz) 626899-001

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

DDR3-SDRAM 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 8 GB of memory configured in a high­performing dual channel mode.

For proper system operation, the DDR3-SDRAM DIMMs must be:

●

industry-standard 240-pin

●

unbuffered non-ECC PC3-10600 DDR3-1333 MHz-compliant

●

1.5 volt DDR3-SDRAM DIMMs

The DDR3-SDRAM DIMMs must also:

●

support CAS latency 9 DDR3 1333 MHz (9-9-9 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.

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.

46 Chapter 6 Removal and Replacement Procedures Microtower (MT) Chassis

●

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 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.

Populating DIMM Sockets

There are four DIMM sockets on the system board, with two sockets per channel.

DIMM Socket Locations

When installing memory modules:

●

If installing only one memory module, install it in DIMM4.

●

If installing 2 memory modules:

◦

2 matching memory modules - install in DIMM4 and DIMM3.

◦

2 non-matching memory modules - install in DIMM4 and DIMM3. Install the larger (GB)
module in DIMM4 and smaller (MB) module in DIMM3.

Black 2

NOTE: A DIMM must occupy the XMM4 socket.

Installing Memory Modules

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.

1. Prepare the computer for disassembly (Preparation for Disassembly on page 43).

2. Remove the access panel (

Access Panel on page 44).

3. Locate the memory module sockets on the system board.

WARNING! To reduce risk of personal injury from hot surfaces, allow the internal system

components to cool before touching.

48 Chapter 6 Removal and Replacement Procedures Microtower (MT) Chassis

4. Open both latches of the memory module socket (1), and insert the memory module into the

socket (2).

Figure 6-4 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.

A DIMM must occupy the DIMM4 socket. Always populate the blue sockets before the black

sockets in each channel.

5. Push the DIMM module down firmly into the socket, ensuring that the module is fully inserted

and properly seated. The DIMM must be pushed all the way down into the socket and sit evenly

in the socket to avoid memory corruption. Make sure the latches are in the closed position (3).

6. Repeat steps 4 and 5 to install any additional modules.

7. Replace the computer access panel.

8. Reconnect the power cord and any external devices, then turn on the computer. The computer

should automatically recognize the additional memory when you turn on the computer.

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

Cable Management

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

●

Keep cables away from major heat sources like the heatsink.

●

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.

●

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

●

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 cable from the white 24-pin 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

Memory Module

Description Spare part number

1-GB memory module (PC2-6400) 626897-001

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

DDR3-SDRAM DIMMs

The memory sockets on the system board can be populated with up to two 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 8-GB of memory.

For proper system operation, the SODIMMs must be:

●

industry-standard 204-pin

●

unbuffered non-ECC PC3-8500 DDR3-1066 MHz-compliant or PC3-10600 DDR3-1333 MHz­compliant

●

1.5 volt DDR3-SDRAM SODIMMs

The DDR3-SDRAM SODIMMs must also:

●

support CAS latency 7 DDR3 1066 MHz (7-7-7 timing) and CAS latency 9 DDR3 1333 MHz
(9-9-9 timing)

●

contain the mandatory Joint Electronic Device Engineering Council (JEDEC) specification

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.

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 memory capacity of the
SODIMM in Channel A is equal to the memory capacity of the SODIMM in Channel B.

●

The system will operate in flex mode if the memory capacity of the SODIMM in Channel A is not
equal to the memory capacity of the SODIMM in Channel B. In flex mode, the channel populated
with the least amount of memory describes the total amount of memory assigned to dual

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

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 SODIMM in the
system.

Populating DIMM Sockets

There are two SODIMM sockets on the system board, with one socket per channel. The sockets are
labeled XMM1 and XMM3. The XMM1 socket operates in memory channel A. The XMM3 socket
operates in memory channel B.

DIMM Socket Locations

When installing memory modules:

●

If installing only one memory module, install it in XMM1.

●

If installing 2 memory modules:

◦

2 matching memory modules - install in XMM1 and XMM2.

◦

2 non-matching memory modules - install in XMM1 and XMM2. Install the larger (GB)
module in XMM1 and smaller (MB) module in XMM2.

Installing SODIMMs

CAUTION: You must disconnect the power cord 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.

1. Prepare the computer for disassembly (Preparation for Disassembly on page 77).

2. Remove the access panel (
