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.

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 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.

Diagnostics
Interpreting Diagnostic Beep Codes
The Power-On Self-Test (POST) is a series of diagnostic tests that runs automatically when the
computer is powered on. If the POST detects an error, this causes an audible beep code to sound.
The POST beep codes are not necessarily accompanied by an associated, visble error code or text
message.
The following table shows the POST beep codes, their meanings, and the recommended actions for
solving the problem.
WARNING! When the computer is plugged into an AC power source, voltage is always applied to
the system board. 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.

Testing Memory Modules
A faulty memory module or socket can lead to memory errors, operating system crashes, or frequent
system lock-ups. Memory problems can be caused by overheating, problems with the power supply,
or corrosion between the memory module and socket that weakens the electrical connection.
HP System Diagnostics allows the user to run tests on the system’s hard drive, memory, and CPU.
The diagnostic tool can check DIMMs to find out whether they are improperly configured, incorrectly
installed, or defective.
To access HP Diagnostic Tools, the user presses the F9 button when booting the PC.
If HP Diagnostic Tools or POST beep codes indicate a memory error, check the following common
memory issues before assuming that the DIMM is faulty.
Reason
Result
Remedy
Improperly configured
The user did not follow the proper
configuration rules and might have the
wrong part for the system.
Check the part number and make sure that the
DIMMs are compatible with the system.
Accessing HP Insight Diagnostics
67
Improperly installed
The DIMM is not seated properly or a
DIMM socket is bad or unusable.
Open the computer casing and reseat the DIMM. If
this does not work, try different sockets.
Check that no debris or corrosion is in the socket.
Defective
If the above remedies do not solve the
DIMM issue, the DIMM could be
defective.
Replace the DIMM.
POST Error/Warning Messages
Once the display becomes available, the BIOS should classify all errors detected during POST into 3
categories and handle them as specified below:
●
Critical errors requiring system shutdown (e.g. CPU fan fault):
Clear the screen, display the corresponding error message, pause for a while as specified and
then turn the system off.
●
Serious errors requiring user's attention and response (e.g. SMART error during POST):
Display the corresponding error message, wait for the user's input and then proceed as selected.
●
Alerts/warnings requiring user's attention (e.g. CMOS checksum error -> defaults loading):
Display the corresponding message and pause for a while as specified. If the message includes
an option for a keystroke from the user and the user responds with the key input, proceed as
selected. Otherwise, continue the POST process.
When there are multiple errors happened during POST, apply the following guideline:
●
If multiple errors include at least one critical error, the system will shut down immediately after
handling the first critical error.
●
If multiple errors do not include a critical error, handle all serious errors first, one by one, and
then proceed to alerts/warnings. For example, if the BIOS detected a SMART error (serious
error), a floppy diskette failure (serious error) and a CMOS checksum error (alert/warning) during
POST, the BIOS will handle them as follows:
For SKUs including an OS=MSV or an OS=LX in the SMBIOS Type 11 data,
1.
Handle the first serious error, SMART error, as follows:
Display "xxx: Hard disk failure is imminent ... Press F10 for Setup, F2 to Continue”. If the
user selects F10, proceed to Setup. However, if the user selects F2, the BIOS should
proceed to step 2 below.
2.
Handle the second serious error, floppy diskette failure, as follows:
Display "Floppy diskette failure ... Press F10 for Setup, F2 to Continue”. If the user selects
F10, proceed to Setup. However, if the user selects F2, the BIOS should proceed to step 3
below.
3.
68
Handle the alert/warning message, CMOS checksum error, as follows:
Appendix B Diagnostics
Display "Default BIOS settings have been loaded... Press F10 for Setup, F2 to Continue”. If
the user selects F10, proceed to Setup. However, if the user selects F2, the BIOS should
proceed to step 2 below.
For all other SKUs,
Use F1 instead of F10 in the above handling.
NOTE: If a device fails to respond while the BIOS tries to configure the device during POST, the
BIOS must not make the system look as if it locked up by having an infinite loop or waiting for too
long. Instead, the BIOS must time out after a reasonable amount of time (the time varies with the
device) and skip to the next process.
NOTE: Unless specified in this document as above, the BIOS should not stop the POST process
with any POST diagnostic screen and/or error message to draw user’s attention. For example, HP
does not consider replacing a hard drive or CPU as an error condition.
Power Button/Power Button LED
The power button is under the BIOS control during POST, in BIOS Setup and after booting to a nonACPI OS. The BIOS must respond immediately when the power button is pressed in these
environments. For the ACPI-compliant OS such as Windows, the BIOS must pass the power button
information to the OS via the ACPI table as specified in the ACPI spec.
If a platform offers a dual-color-based power button LED, the BIOS will program the power button
LED to alternate the color between the On (ACPI S0) state and the Stand-by (S3) state. In doing so,
the LED should not blink, but stay constant. Check with the corresponding platform manager for the
default colors in the On and Stand-by states. The color of the power button LED in the Hibernate
state (ACPI S4) is the same as in the S5 state.
To find out if the system's power button LED is dual-color capable, check the SMBIOS Type 11 data
structure. If the SMBIOS Type 11 data structure contains the string DLED (NOT case-sensitive), the
system supports the dual-color power button LED and therefore, the BIOS support as described
above is required.
Using the Setup Utility
The BIOS Setup Utility is accessed by pressing the F10 button during startup. The BIOS Setup Utility
allows you to:
●
Change factory default settings
●
Set the system date and time
●

Routine Care 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 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.
●
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.
●
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.

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.
Appendix E Routine Care and Disassembly Preparation
●
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 90
●
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.
NOTE: Batteries, battery packs, and accumulators should not be disposed of together with the
general household waste. In order to forward them to recycling or proper disposal, please use the
public collection system or return them to HP, their authorized partners, or their agents.

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.
98
Appendix F 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.

Power Cord Set Requirements
The power supplies on some computers have external power switches. The voltage select switch
feature on the computer permits it to operate from any line voltage between 100-120 or 220-240 volts
AC. Power supplies on those computers that do not have external power switches are equipped with
internal switches that sense the incoming voltage and automatically switch to the proper voltage.
The power cord set received with the computer meets the requirements for use in the country where
you purchased the equipment.
Power cord sets for use in other countries must meet the requirements of the country where you use
the computer.
General Requirements
The requirements listed below are applicable to all countries:
1.
The power cord must be approved by an acceptable accredited agency responsible for
evaluation in the country where the power cord set will be installed.
2.
The power cord set must have a minimum current capacity of 10A (7A Japan only) and a
nominal voltage rating of 125 or 250 volts AC, as required by each country’s power system.
3.
The diameter of the wire must be a minimum of 0.75 mm2 or 18AWG, and the length of the cord
must be between 1.8 m (6 feet) and 3.6 m (12 feet).
The power cord should be routed so that it is not likely to be walked on or pinched by items placed
upon it or against it. Particular attention should be paid to the plug, electrical outlet, and the point
where the cord exits from the product.
WARNING! Do not operate this product with a damaged power cord set. If the power cord set is
