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.

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.

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

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.

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.

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.

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.
46
●
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.
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.

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.

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

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.

●
Keep cables away from major heat sources.
●
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 pre-folded. 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.

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.
82
●
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
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

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 (Access Panel on page 78).
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.
4.
If you are adding a second SODIMM, remove the SODIMM from the top XMM1 socket to access
the bottom XMM2 socket. Press outward on the two latches on each side of the SODIMM (1)
then pull the SODIMM out of the socket (2).

Chapter 10 Computer Diagnostic Features
Test Tab
The Test tab allows you to choose various parts of the system to test. You can also choose the type
of test and testing mode.
There are three types of tests to choose from:
●
Quick Test—Provides a predetermined script where a sample of each hardware component is
exercised. You may further modify which of the Quick tests are executed by selecting or
deselecting individual tests in the hardware component check list.
●
Complete Test—Provides a predetermined script where each hardware component is fully
tested. You may further modify which of the Complete tests are executed by selecting or
deselecting individual tests in the hardware component check list.
●
Custom Test—Provides the most flexibility in controlling the testing of a system. The Custom
Test mode allows you to specifically select which devices, tests, and test parameters are run.
By default, the three test modes do not display prompts and require no interaction. If errors are found,
they are displayed when testing is complete.
However, for each test type, you may also optionally add interactive tests by clicking the Include
interactive tests box under Test mode. Selecting interactive tests provides the maximum control
over the testing process. The diagnostic software will prompt you for input during tests.

Resetting the Password Jumper
This computer supports two security password features, which can be established through the
Computer Setup Utilities menu: supervisor password and user password
To disable the password features, or to clear the 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.
2.
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.
