3 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 nger 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 aected 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.

●
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.
Electrostatic discharge information 15
Personal grounding methods and equipment
Use the following equipment to prevent static electricity damage to equipment:
●
Wrist straps are exible 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 t 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 oors or dissipative oor mats, use them on both feet with
a maximum of one-megohm ± 10% resistance between the operator and ground.

Antistatic plastic
Carbon-loaded plastic
Metallized laminate
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 o power and input signals before inserting and removing connectors or test equipment.
●
Use xtures made of static-safe materials when xtures must directly contact dissipative surfaces.
●
Keep work area free of nonconductive materials such as ordinary plastic assembly aids and Styrofoam.
●
Use eld 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 airow.
●
Never restrict the airow 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 airow.
●
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 airow. 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 ammable 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.
Operating guidelines 17
Cleaning the Computer Case
Follow all safety precautions in General cleaning safety precautions on page 17 before cleaning the computer.
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 airow.
Cleaning the keyboard
Follow all safety precautions in General cleaning safety precautions on page 17 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 18.
When cleaning debris from under the keys, review all rules in General cleaning safety precautions on page 17
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
bers or dirt in conned 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 ammable liquids on the monitor.
●
To clean the monitor body follow the procedures in Cleaning the Computer Case on page 18.

Screws
The screws used in the computer are not interchangeable. They may have standard or metric threads and may
be of dierent 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 nish. U.S. screws have a silver nish 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 at, exible 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.
Service considerations 19
●
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 o 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 14
●
Do not use excessive force when inserting a drive.
●
Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic elds
such as monitors or speakers.

SATA hard drive cables
SATA data cable
Always use an HP approved SATA 6.0 Gb/s cable as it is fully backwards compatible with the SATA 1.5 Gb/s
drives.
Current HP desktop products ship with SATA 6.0 Gb/s hard drives.
SATA data cables are susceptible to damage if overexed. 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.
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 at ribbon cable, never fold to a sharp crease. Sharp creases may damage the wires.
●
Some at 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.
