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. The power cord must be disconnected 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.
Generating static
The following table shows how humidity aects the electrostatic voltage levels generated by dierent
activities. A product can be degraded by 700 volts.
●
Dierent activities generate dierent amounts of static electricity.
●
Static electricity increases as humidity decreases.

Electrostatic discharge information 9
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-sensitive 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 containers.
●
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 exible straps with a maximum of one-megohm ± 10% resistance in the ground cords.
To provide proper ground, a strap must be worn snugly against bare skin. The ground cord must be
connected to the banana plug connector on the grounding mat or workstation and t snugly into it.
●
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.
Method Voltage

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.
Operating guidelines 11
●
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.

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 the surface
with a cloth or swab dampened with clear water.
●
For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed; alcohol will evaporate quickly
without leaving 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 12 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 12.
When cleaning debris from under the keys, review all rules in General cleaning safety precautions on page 12
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.
12 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation
●
If you want to remove a key, use a specially designed key puller to prevent damage to the keys. This tool
is available through many electronics supply outlets.
CAUTION: Never remove a wide, level 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 then 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 towelette designed for cleaning monitors or with a clean cloth
moistened with water. 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 12.
Service considerations
Listed below are some of the considerations that you should keep in mind during the disassembly and
assembly of the computer.
Tools and software requirements
Screws
To service the computer, you need the following:
●
Diagnostics software
●
Flat-bladed screwdriver (may sometimes be used in place of a Torx screwdriver)
●
Phillips #2 screwdriver
●
Torx15 screwdriver
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: As each subassembly is removed from the computer, it should be placed away from the work area
to prevent damage.
Service considerations 13
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.
●
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 computer.
●
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.
●
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 CRT monitors or speakers.
