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 Windows operating system
The first time you turn on the computer, the operating system is installed automatically. This process
takes about 5 to 10 minutes. Carefully read and follow the instructions on the screen to complete the
installation.
CAUTION: After 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.
Installing the Windows operating system 7
Downloading Windows 7 updates
Microsoft may release updates to the operating system. To help keep the computer running optimally,
HP recommends checking for the latest updates during the initial installation and periodically
throughout the life of the computer.
1. To set up your Internet connection, click Start > Internet Explorer and follow the instructions on

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, SMART.
●
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 CD-
●
ROM).
NOTE: Displays for USB diskette drives.
Default Values (ATA disks only)

See Translation Mode above for details.
SATA Defaults
12 Chapter 3 Computer Setup (F10) Utility
Table 3-3 Computer Setup—Storage (continued)
Storage Options 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).
Legacy IDE - This is the most backwards-compatible setting of the three options. Operating
systems usually do not require additional driver support in IDE mode.
IDE Mode- Allows software to communicate with the SATA controller like a traditional PATA
controller using natively assigned PCI resources. The difference between it and Legacy Mode IDE
is that legacy mode uses the legacy resources for PATA controllers (IRQs 14 and 15, I/Os
1F0h-1F7h, 3F6h, 170h-177h, etc.).
RAID Mode - 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 Mode (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.
eSATA Port (some models)
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
Max eSATA Speed (some models; default is Auto)
Allows you to choose Auto, 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.
Removable Media Boot
Enables/disables ability to boot the system from removable media. Default is enabled.

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

5 Routine Care, SATA Drive Guidelines,
and Disassembly Preparation
This chapter provides general service information for the computer. Adherence to the procedures and
precautions described in this chapter is essential for proper service.
CAUTION: When the computer is plugged into an AC power source, voltage is always applied to
the system board. You must disconnect the power cord from the power source before opening the
computer to prevent system board or component damage.
Electrostatic Discharge Information
A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive
devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic
device exposed to electrostatic discharge (ESD) may not appear to be affected at all and can work
perfectly throughout a normal cycle. The device may function normally for a while, but it has been
degraded in the internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the
discharge contains enough power to alter device parameters or melt silicon junctions.
Generating Static
The following table shows that:
Different activities generate different amounts of static electricity.

Preventing Electrostatic Damage to Equipment
Many electronic components are sensitive to ESD. Circuitry design and structure determine the
degree of sensitivity. The following packaging and grounding precautions are necessary to prevent
damage to electric components and accessories.
To avoid hand contact, transport products in static-safe containers such as tubes, bags, or
●
boxes.
Protect all electrostatic parts and assemblies with conductive or approved containers or
●
packaging.
Keep electrostatic sensitive parts in their containers until they arrive at static-free stations.
●
Place items on a grounded surface before removing them from their container.
●

Always be properly grounded when touching a sensitive component or assembly.
●
Avoid contact with pins, leads, or circuitry.
●
Place reusable electrostatic-sensitive parts from assemblies in protective packaging or
●
conductive foam.
Personal Grounding Methods and Equipment
Use the following equipment to prevent static electricity damage to equipment:
● Wrist straps are flexible straps with a maximum of one-megohm ± 10% resistance in the ground
cords. To provide proper ground, a strap must be worn snug against bare skin. The ground cord
must be connected and fit snugly into the banana plug connector on the grounding mat or
workstation.
Heel straps/Toe straps/Boot straps can be used at standing workstations and are compatible
●
with most types of shoes or boots. On conductive floors or dissipative floor mats, use them on
both feet with a maximum of one-megohm ± 10% resistance between the operator and ground.

Grounding the Work Area
To prevent static damage at the work area, use the following precautions:
● 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.
Use field service tools, such as cutters, screwdrivers, and vacuums, that are conductive.

Operating Guidelines
To prevent overheating and to help prolong the life of the computer:
Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and
●
cold.
Operate the computer on a sturdy, level surface. Leave a 10.2-cm (4-inch) clearance on all
●
vented sides of the computer and above the monitor to permit the required airflow.
Never restrict the airflow into the computer by blocking any vents or air intakes. Do not place the
●
keyboard, with the keyboard feet down, directly against the front of the desktop unit as this also
restricts airflow.
Occasionally clean the air vents on all vented sides of the computer. Lint, dust, and other foreign
●
matter can block the vents and limit the airflow. Be sure to unplug the computer before cleaning
the air vents.
Never operate the computer with the cover or side panel removed.
●
Do not stack computers on top of each other or place computers so near each other that they
●
are subject to each other’s re-circulated or preheated air.
If the computer is to be operated within a separate enclosure, intake and exhaust ventilation
●
must be provided on the enclosure, and the same operating guidelines listed above will still
apply.
Keep liquids away from the computer and keyboard.
●
Never cover the ventilation slots on the monitor with any type of material.
●
Install or enable power management functions of the operating system or other software,
●
including sleep states.
Routine Care
General Cleaning Safety Precautions
1. Never use solvents or flammable solutions to clean the computer.
2. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and
then use the cloth on the component.
3. Always unplug the computer when cleaning with liquids or damp cloths.
4. Always unplug the computer before cleaning the keyboard, mouse, or air vents.
5. Disconnect the keyboard before cleaning it.
6. Wear safety glasses equipped with side shields when cleaning the keyboard.
Cleaning the Computer Case
Follow all safety precautions in General Cleaning Safety Precautions on page 43 before cleaning the
computer.
Operating Guidelines 43
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 43 before cleaning the
keyboard.
To clean the tops of the keys or the keyboard body, follow the procedures described in
Computer Case on page 43.
When cleaning debris from under the keys, review all rules in
on page 43 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
Cleaning the
General Cleaning Safety Precautions
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
●
44 Chapter 5 Routine Care, SATA Drive Guidelines, and Disassembly Preparation
Cleaning the Computer Case on page 43.
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
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.
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)
●
Cleaning the Computer Case on page 43.
Screws
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 tamper-
●
resistant bits (Smart Cover FailSafe Key, PN 166527-002)
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.
Service Considerations 45
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
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.

SATA Hard Drive Cables
SATA Data Cable
Always use an HP approved SATA 3.0 Gb/s cable as it is fully backwards compatible with the SATA
1.5 Gb/s drives.
Current HP desktop products ship with SATA 3.0 Gb/s hard drives.
SATA data cables are susceptible to damage if overflexed. Never crease a SATA data cable and
never bend it tighter than a 30 mm (1.18 in) radius.
The SATA data cable is a thin, 7-pin cable designed to transmit data for only a single drive.
SMART ATA Drives
The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for the HP Personal
Computers have built-in drive failure prediction that warns the user or network administrator of an
impending failure or crash of the hard drive. The SMART drive tracks fault prediction and failure
indication parameters such as reallocated sector count, spin retry count, and calibration retry count. If
the drive determines that a failure is imminent, it generates a fault alert.
Cable Management
Always follow good cable management practices when working inside the computer.
Keep cables away from major heat sources like the heat sink.
●
● Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these
are not designed to take excessive pressure on them.
Keep cables clear of sliding or moveable parts to prevent them from being cut or crimped when
●
the parts are moved.
When folding a flat ribbon cable, never fold to a sharp crease. Sharp creases may damage the
●
wires.
SATA Hard Drives 47
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.
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.

Memory
Description Spare part number
8-GB, PC3-12800 689375-001
4-GB, PC3-12800 671613-001
2-GB, PC3-12800 671612-001
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3SDRAM) dual inline memory modules (DIMMs).
DIMMs
The memory sockets on the system board can be populated with up to four industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to 16-GB of memory configured in a
high-performing dual channel mode.
DDR3-SDRAM DIMMs
CAUTION: This product DOES NOT support DDR3 Ultra Low Voltage (DDR3U) memory. The
processor is not compatible with DDR3U memory and if you plug DDR3U memory into the system
board, it can cause the physical damage to the DIMM or invoke system malfunction.
For proper system operation, the DDR3-SDRAM DIMMs must be:
industry-standard 240-pin
●
unbuffered non-ECC PC3-PC14800 DDR3-1866 MHz-compliant
●
1.5 volt DDR3-SDRAM DIMMs
●
The DDR3-SDRAM DIMMs must also:
support CAS latency 13 DDR3 1866 MHz (13-13-13 timing)
●
contain the mandatory JEDEC SPD information
●
In addition, the computer supports:
512-Mbit, 1-Gbit, 2-Gbit, 4-Gbit, and 8-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.
Memory 55
Populating DIMM Sockets
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are
labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory
channel B. Sockets DIMM3 and DIMM4 operate in memory channel A.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.
NOTE: Single channel and unbalanced dual channel memory configurations will result in inferior
graphics performance.
The system will operate in single channel mode if the DIMM sockets are populated in one
●
channel only.
The system will operate in a higher-performing dual channel mode if the total memory capacity
●
of the DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B.
The technology and device width can vary between the channels. For example, if Channel A is
populated with two 1-GB DIMMs and Channel B is populated with one 2-GB DIMM, the system
will operate in dual channel mode.
The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is
●
not equal to the total memory capacity of the DIMMs in Channel B. In flex mode, the channel
populated with the least amount of memory describes the total amount of memory assigned to
dual channel and the remainder is assigned to single channel. For optimal speed, the channels
should be balanced so that the largest amount of memory is spread between the two channels.
If one channel will have more memory than the other, the larger amount should be assigned to
Channel A. For example, if you are populating the sockets with one 2-GB DIMM, and three 1-GB
DIMMs, Channel A should be populated with the 2-GB DIMM and one 1-GB DIMM, and Channel
B should be populated with the other two 1-GB DIMMs. With this configuration, 4-GB will run as
dual channel and 1-GB will run as single channel.
In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
●
Installing DIMMs
CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power
to drain before adding or removing memory modules. Regardless of the power-on state, voltage is
always supplied to the memory modules as long as the computer is plugged into an active AC outlet.
Adding or removing memory modules while voltage is present may cause irreparable damage to the
memory modules or system board.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is
important to use memory modules with gold-plated metal contacts to prevent corrosion and/or
oxidation resulting from having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before
beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object. For more information, refer to
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.
