3 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 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.

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.
Operating guidelines
13
●
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.

●
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 14 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 14.

General cleaning safety precautions
on page 14 before following these procedures:
14 Chapter 3 Routine care and disassembly preparation
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 14.
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.

Tamper-resistant T-15 wrench
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.
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

The memory sockets on the system board can be populated with up to two industry-standard
SODIMMs. These memory sockets are populated with at least one preinstalled SODIMM. To achieve
the maximum memory support, you can populate the system board with up to 16-GB of memory.
DDR3-SDRAM SODIMMs
For proper system operation, the SODIMMs must be:
●
industry-standard 204-pin
●
unbuffered non-ECC PC3-12800 DDR3-1600 MHz-compliant
●
1.35 volt or 1.5 volt DDR3-SDRAM SODIMMs
The DDR3-SDRAM SODIMMs must also:
●
support CAS latency 11 DDR3 1600 MHz (11-11-11 timing)
●
contain the mandatory Joint Electronic Device Engineering Council (JEDEC) specification
In addition, the computer supports:
●
512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies
●
single-sided and double-sided SODIMMS
●
SODIMMs constructed with x8 and x16 devices; SODIMMs constructed with x4 SDRAM are not
supported
NOTE: The system will not operate properly if you install unsupported SODIMMs.
