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.
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.

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.
Recommended Materials and Equipment

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

●
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:
Routine Care
23
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 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.
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.

Chapter 5 Identifying the Chassis, Routine Care, and Disassembly Preparation
Tools and Software Requirements
To service the computer, you need the following:
●
Torx T-15 screwdriver (HP screwdriver with bits, PN 161946-001)
●
Torx T-15 screwdriver with small diameter shank (for certain front bezel removal)
●
Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver)
●
Phillips #2 screwdriver
●
Diagnostics software
●
HP tamper-resistant T-15 wrench (Smart Cover FailSafe Key, PN 166527-001) or HP tamperresistant bits (Smart Cover FailSafe Key, PN 166527-002)
Screws
The screws used in the computer are not interchangeable. They may have standard or metric threads
and may be of different lengths. If an incorrect screw is used during the reassembly process, it can
damage the unit. HP strongly recommends that all screws removed during disassembly be kept with
the part that was removed, then returned to their proper locations.
CAUTION: Metric screws have a black finish. U.S. screws have a silver finish and are used on hard
drives only.
CAUTION: As each subassembly is removed from the computer, it should be placed away from the
work area to prevent damage.
Cables and Connectors
Most cables used throughout the unit are flat, flexible cables. These cables must be handled with
care to avoid damage. Apply only the tension required to seat or unseat the cables during insertion or
removal from the connector. Handle cables by the connector whenever possible. In all cases, avoid
bending or twisting the cables, and ensure that the cables are routed in such a way that they cannot
be caught or snagged by parts being removed or replaced.
CAUTION: When servicing this computer, ensure that cables are placed in their proper location
during the reassembly process. Improper cable placement can damage the computer.
Hard Drives
Handle hard drives as delicate, precision components, avoiding all physical shock and vibration. This
applies to failed drives as well as replacement spares.
●
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.
Service Considerations
25
●
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.
Lithium Coin Cell Battery
The battery that comes with the computer provides power to the real-time clock and has a minimum
lifetime of about three years.
See the appropriate removal and replacement chapter for the chassis you are working on in this
guide for instructions on the replacement procedures.
WARNING! This computer contains a lithium battery. There is a risk of fire and chemical burn if the
battery is handled improperly. Do not disassemble, crush, puncture, short external contacts, dispose
in water or fire, or expose it to temperatures higher than 140ºF (60ºC). Do not attempt to recharge the
battery.

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 two 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.
DDR3-SDRAM DIMMs
For proper system operation, the DDR3-SDRAM DIMMs must be:
●
industry-standard 240-pin
●
unbuffered non-ECC PC3-12800 DDR3-1600 MHz-compliant
●
1.5 volt DDR3-SDRAM DIMMs
The DDR3-SDRAM DIMMs must also:
●
support CAS latency 11 DDR3 1600 MHz (11-11-11 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.
Installing Additional Memory
43
Populating DIMM Sockets
There are two DIMM sockets on the system board: XMM1 and XMM3 with one socket per Channel.
XMM3 operates in memory channel A. XMM1 operates in memory Channel B.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.
●
The system will operate in single channel mode if the DIMM sockets are populated in one
channel only.
●
The system will operate in a higher-performing dual channel mode if the total memory capacity
of the DIMM in Channel A is equal to the total memory capacity of the DIMM in Channel B.
●
The system will operate in flex mode if the total memory capacity of the DIMM in Channel A is
not equal to the total memory capacity of the DIMM in Channel B. In flex mode, the channel
populated with the least amount of memory describes the total amount of memory assigned to
dual channel and the remainder is assigned to single channel. If one channel will have more
memory than the other, the larger amount should be assigned to Channel A.
●
In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
Installing DIMMs
CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power
to drain before adding or removing memory modules. Regardless of the power-on state, voltage is
always supplied to the memory modules as long as the computer is plugged into an active AC outlet.
Adding or removing memory modules while voltage is present may cause irreparable damage to the
memory modules or system board.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is
important to use memory modules with gold-plated metal contacts to prevent corrosion and/or
oxidation resulting from having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before
beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.

Cable Management
The Small Form Factor chassis is a very compact computer and proper routing of the internal cables
is critical to the operation of the computer. Follow good cable management practices when working
inside the computer.
●
Keep cables away from major heat sources like the heat sink.
●
Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these
are not designed to take excessive pressure on them.
●
Keep cables clear of movable or rotating parts like the power supply and drive cage to prevent
them from being cut or crimped when the component is lowered into its normal position.
●
When folding a flat ribbon cable, never fold to a sharp crease. Sharp creases may damage the
wires.
●
Some flat ribbon cables come prefolded. Never change the folds on these cables.
●
Do not bend any cable sharply. A sharp bend can break the internal wires.
●
Never bend a SATA data cable tighter than a 30 mm (1.18 in) radius.
●
Never crease a SATA data cable.
●
Do not rely on components like the drive cage, power supply, or computer cover to push cables
down into the chassis. Always position the cables to lay properly by themselves.
When removing the power supply power cables from the connector on the system board, always
follow these steps:
1.
Squeeze on the top of the retaining latch attached to the cable end of the connector (1).
2.
Grasp the cable end of the connector and pull it straight up (2).
CAUTION: Always pull the connector - NEVER pull on the cable. Pulling on the cable could
damage the cable and result in a failed power supply.

Installing and Removing Drives
When installing additional drives, follow these guidelines:
NOTE: Refer to System Board Connections on page 42 for an illustration of the system board drive
connectors.
●
The primary Serial ATA (SATA) hard drive must be connected to the dark blue primary SATA
connector on the system board labeled SATA0.
●
Connect a SATA optical drive to the white SATA connector on the system board labeled SATA1.
●
Connect a media card reader USB cable to the USB connector on the system board labeled
MEDIA1.
●
The power cable for the SATA drives is a three-headed cable that is plugged into the system
board with the first connector routed to the rear of the hard drive, the second connector routed to
the rear of the 3.5” drive, and the third connector routed to the rear of the 5.25” optical drive.
●
The system does not support Parallel ATA (PATA) optical drives or PATA hard drives.
●
You must install mounting screws to ensure the drive will line up correctly in the drive cage and
lock in place. HP has provided extra mounting screws for the internal drive bays (five 6-32
standard screws and four M3 metric screws), installed in the front of the chassis, under the front
bezel. The 6-32 standard screws are required for a secondary hard drive (not supported). All
other drives (except the primary hard drive) use M3 metric screws. The HP-supplied metric
screws are black and the HP-supplied standard screws are silver.

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.
NOTE: The memory count will be affected by configurations with the Management Engine (ME)
enabled. The ME uses 8MB of system memory in single channel mode or 16MB of memory in dualchannel mode to download, decompress, and execute the ME firmware for Out-of-Band (OOB), thirdparty data storage, and other management functions.

Password Security and Resetting
CMOS
This computer supports security password features, which can be established through the Computer
Setup Utilities menu.
This computer supports two security password features that are established through the Computer
Setup Utilities menu: setup password and power-on password. When you establish only a setup
password, any user can access all the information on the computer except Computer Setup. When
you establish only a power-on password, the power-on password is required to access Computer
Setup and any other information on the computer. When you establish both passwords, only the
setup password will give you access to Computer Setup.
When both passwords are set, the setup password can also be used in place of the power-on
password as an override to log in to the computer. This is a useful feature for a network administrator.
If you forget the password for the computer, you can clear that password so you can gain access to
the information on the computer by resetting the password jumper.
CAUTION: Pushing the CMOS button will reset CMOS values to factory defaults. It is important to
back up the computer CMOS settings before resetting them in case they are needed later. Back up is
easily done through Computer Setup. See the Computer Setup (F10) Utility Guide for information on
backing up the CMOS settings.

Drive Protection System (DPS)
The Drive Protection System (DPS) is a diagnostic tool built into the hard drives installed in some
computers. DPS is designed to help diagnose problems that might result in unwarranted hard drive
replacement.
When these systems are built, each installed hard drive is tested using DPS, and a permanent record
of key information is written onto the drive. Each time DPS is run, test results are written to the hard
drive. Your service provider can use this information to help diagnose conditions that caused you to
run the DPS software.
Running DPS will not affect any programs or data stored on the hard drive. The test resides in the
hard drive firmware and can be executed even if the computer will not boot to an operating system.
The time required to execute the test depends on the manufacturer and size of the hard drive; in most
cases, the test will take approximately two minutes per gigabyte.
Use DPS when you suspect a hard drive problem. If the computer reports a SMART Hard Drive
Detect Imminent Failure message, there is no need to run DPS; instead, back up the information on
the hard drive and contact a service provider for a replacement hard drive.
141
Accessing DPS Through Computer Setup
When the computer does not power on properly you should use Computer Setup to access the DPS
program. To access DPS, perform the following steps:
1.
Turn on or restart the computer.
2.
When the F10 Setup message appears in the lower-right corner of the screen, press the F10
key.
NOTE: If you do not press the F10 key while the message is displayed, you must turn the
computer off, then on again, to access the utility.
A choice of five headings appears in the Computer Setup Utilities menu: File, Storage,
Security, Power, and Advanced.
3.
Select Storage > DPS Self-Test.
The screen will display the list of DPS-capable hard drives that are installed on the computer.
NOTE: If no DPS-capable hard drives are installed, the DPS Self-Test option will not appear
on the screen.
4.
Select the hard drive to be tested and follow the screen prompts to complete the testing process.
When the test has been completed, one of three messages will be displayed:
●
Test Succeeded. Completion Code 0.
●
Test Aborted. Completion Code 1 or 2.
●
Test Failed. Drive Replacement Recommended. Completion Code 3 through 14.
If the test failed, the completion code should be recorded and reported to your service provider for
help in diagnosing the computer problem.

Recovery media
You should create a set of recovery discs, or a recovery USB flash drive, from the recovery image
stored on your hard disk drive. This image contains the operating system and software program files
that were originally installed on your computer at the factory. You can create only one set of recovery
discs, or one recovery USB flash drive, for your computer; the recovery discs, or the recovery drive,
can be used only with this computer. Store the recovery discs, or the recovery USB flash drive, in a
safe place.
NOTE: Some features might not be available on systems that are shipped without a version of
Microsoft Windows.
Choosing recovery media
●
To create recovery discs, your computer must have a DVD writer, and you must use only highquality blank DVD+R or DVD-R discs.
NOTE: You cannot use CDs or DVD+RW, DVD-RW, DVD+RW DL, DVD-RW DL, DVD+R DL,
or DVD-R DL discs to create recovery discs.
●
You have the option of creating a recovery USB flash drive instead, using a high-quality blank
USB drive.
●
If you are creating recovery discs, be sure to use high-quality discs. It is normal for discs to be
rejected if they are not defect-free. You will be prompted to insert a new blank disc to try again.
●
The number of discs in the recovery-disc set depends on your computer model (typically 3–6
DVD discs). The Recovery Media Creation program tells you the specific number of blank discs
needed to make the set. If you are using a USB flash drive, the program will tell you the size of
the drive required to store all the data (minimum of 8 GB).
NOTE: The process of creating recovery discs, or a recovery USB drive, takes some time to
verify that the information written on the disc, or USB flash drive, is correct. You can quit the
process at any time. The next time you run the program, it resumes where it left off.
Creating recovery media
To create recovery discs:
1.
Close all open programs.
2.
Tap the Start button, tap All Programs, tap Recovery Manager, and then tap Recovery Media
Creation. If prompted, tap Yes to allow the program to continue.
146 Appendix F System Recovery
3.
Tap Create recovery media using blank DVD(s), and then tap Next.
4.
Follow the on-screen instructions. Label each disc as you make it (for example, Recovery 1,
Recovery 2).
To create a recovery USB flash drive:
1.
Close all open programs.
2.
Insert the USB flash drive into a USB port on the computer.
3.
Tap the Start button, tap All Programs, tap Recovery Manager, and then tap Recovery Media
Creation.
4.
Tap Create recovery media with a USB flash drive, and then tap Next.
5.
Select the USB flash drive from the list of media. The program will let you know how much
storage is required to create the recovery drive. If the USB flash drive does not have enough
storage capacity (8 GB is the minimum), it will be grayed out on the screen. Tap Next.
NOTE: Recovery Media Creation formats the flash drive and deletes all on files on it.
6.
Follow the on-screen instructions. Make sure to label the USB flash drive and store it in a secure
place.
NOTE: Do not use media cards for creating recovery media. The system may not be able to boot up
from a media card and you may not be able to run system recovery.
