(3-inch) clearance on the left and right sides of the computer.
The computer uses an electric fan for ventilation. The fan is
controlled by a temperature sensor and is designed to be turned
on automatically when high temperature conditions exist. These
conditions are affected by high external temperatures, system
power consumption, power management/battery conservation
configurations, battery fast charging, and software applications.
Exhaust air is displaced through the ventilation grill located on
the left side of the computer.

The following sections include some of the considerations
that you should keep in mind during disassembly and assembly
procedures.
As you remove each subassembly from the computer, place
✎
the subassembly (and all accompanying screws) away from
the work area to prevent damage.
Plastic Parts
Using excessive force during disassembly and reassembly can
damage plastic parts. Use care when handling the plastic parts.
Apply pressure only at the points designated in the maintenance
instructions.
Cables and Connectors
CAUTION: When servicing the computer, ensure that cables are
Ä
placed in their proper locations during the reassembly process.
Improper cable placement can damage the computer.
Cables must be handled with extreme care to avoid damage.
Apply only the tension required to unseat or seat the cables
during removal and insertion. Handle cables by the connector
whenever possible. In all cases, avoid bending, twisting, or
tearing cables. Ensure that cables are routed in such a way that
they cannot be caught or snagged by parts being removed or
replaced. Handle flex cables with extreme care; these cables
tear easily.

Removal and Replacement Preliminaries
4.3 Preventing Damage to
Removable Drives
Removable drives are fragile components that must be handled
with care. To prevent damage to the computer, damage to a
removable drive, or loss of information, observe the following
precautions:
■ Before removing or inserting a hard drive, shut down the
computer. If you are unsure whether the computer is off or
in hibernation, turn the computer on, and then shut it down
through the operating system.
■ Before removing a diskette drive or optical drive, ensure that
a diskette or disc is not in the drive and ensure that the optical
drive tray is closed.
■ Before handling a drive, ensure that you are discharged of
static electricity. While handling a drive, avoid touching the
connector.
■ Handle drives on surfaces covered with at least one inch of
shock-proof foam.
■ Avoid dropping drives from any height onto any surface.
■ After removing a hard drive, an optical drive, or a diskette
drive, place it in a static-proof bag.
■ Avoid exposing a hard drive to products that have magnetic
fields, such as monitors or speakers.
■ Avoid exposing a drive to temperature extremes or liquids.
■ If a drive must be mailed, place the drive in a bubble pack
mailer or other suitable form of protective packaging and label
the package “FRAGILE: Handle With Care.”
Maintenance and Service Guide4–3
Removal and Replacement Preliminaries
4.4 Preventing Electrostatic Damage
Many electronic components are sensitive to electrostatic
discharge (ESD). Circuitry design and structure determine the
degree of sensitivity. 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.
A sudden discharge of static electricity from a 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 may not
be affected at all and can work perfectly throughout a normal
cycle. Or the device may function normally for a while, then
degrade in the internal layers, reducing its life expectancy.
4–4Maintenance and Service Guide
Removal and Replacement Preliminaries
4.5 Packaging and Transporting
Precautions
Use the following grounding precautions when packaging and
transporting equipment:
■ 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
the parts arrive at static-free workstations.
■ Place items on a grounded surface before removing items
from their containers.
■ Always be properly grounded when touching a sensitive
component or assembly.
■ Store reusable electrostatic-sensitive parts from assemblies
in protective packaging or nonconductive foam.
■ Use transporters and conveyors made of antistatic belts and
roller bushings. Ensure that mechanized equipment used for
moving materials is wired to ground and that proper materials
are selected to avoid static charging. When grounding is not
possible, use an ionizer to dissipate electric charges.
Maintenance and Service Guide4–5
Removal and Replacement Preliminaries
4.6 Workstation Precautions
Use the following grounding precautions at workstations:
■ Cover the workstation with approved static-shielding material
(refer to
■ Use a wrist strap connected to a properly grounded work
surface and use properly grounded tools and equipment.
■ Use conductive field service tools such as cutters,
screwdrivers, and vacuums.
■ When fixtures must directly contact dissipative surfaces, use
fixtures made only of static-safe materials.
■ Keep the work area free of nonconductive materials such
as ordinary plastic assembly aids and Styrofoam.
■ Handle electrostatic-sensitive components, parts, and
assemblies by the case or PCM laminate. Handle these
items only at static-free workstations.
■ Avoid contact with pins, leads, or circuitry.
■ Turn off power and input signals before inserting or removing
connectors or test equipment.
Table 4-2, “Static-Shielding Materials”).
4.7 Grounding Equipment and
Methods
Grounding equipment must include either a wrist strap or a
foot strap at a grounded workstation.
■ When seated, wear a wrist strap connected to a grounded
system. Wrist straps are flexible straps with a minimum of
one megohm ±10% resistance in the ground cords. To provide
proper ground, wear a strap snugly against the skin at all times.
On grounded mats with banana-plug connectors, use alligator
clips to connect a wrist strap.
4–6Maintenance and Service Guide
Removal and Replacement Preliminaries
■ When standing, use foot straps and a grounded floor mat.
Foot straps (heel, toe, or 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
foot straps on both feet with a minimum of one megohm
resistance between the operator and ground. To be effective,
the conductive strips must be worn in contact with the skin.
Other grounding equipment recommended for use in preventing
electrostatic damage includes:
■ Antistatic tape
■ Antistatic smocks, aprons, and sleeve protectors
■ Conductive bins and other assembly or soldering aids
■ Nonconductive foam
■ Conductive tabletop workstations with ground cords of
one megohm resistance
■ Static-dissipative tables or floor mats with hard ties to
the ground
■ Field service kits
■ Static awareness labels
■ Material-handling packages
■ Nonconductive plastic bags, tubes, or boxes
■ Metal tote boxes
■ Electrostatic voltage levels and protective materials
