1.4 Design Overview
This section presents a design overview of key parts and features
of the computer. Refer to Chapter 3, “Illustrated Parts Catalog”
and Chapter 5, “Removal and Replacement Procedures.”
The system board provides the following device connections:
■Memory expansion board
■Hard drive
■Display
■Keyboard/TouchPad
■Audio
■Intel Pentium III or Intel Celeron Processors
■Fan
■PC Card
■Modem or modem/NIC
■Microphone
The computer uses an electrical fan for ventilation. The fan is
controlled by a temperature sensor and is designed to turn 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 right side of the computer.
CAUTION: To properly ventilate the computer, allow at least a 3-inch
Ä
(7.6 cm) clearance on the left and right sides of the computer.

Listed below are some of the considerations that you should keep
in mind during disassembly and assembly procedures.
As you remove each subassembly from the computer, place it
✎
(and all accompanying screws) away from the work area to
prevent damage.
Maintenance and Service Guide4–1
Page 59
Removal and Replacement Preliminaries
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
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; they tear easily.
CAUTION: When servicing the computer, ensure that cables are
Ä
placed in their proper location during the reassembly process.
Improper cable placement can damage the computer.
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 these
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, then shut it down.
■Before removing a diskette drive or optical drive, ensure that
a diskette or disc is not in the drive. Ensure that the optical
drive tray is closed.
4–2Maintenance and Service Guide
Page 60
Removal and Replacement Preliminaries
■Before handling a drive, ensure that you are discharged of
static electricity. While handling a drive, avoid touching the
connector.
■Handle drives on surfaces that have at least one inch of
shock-proof foam.
■Avoid dropping drives from any height onto any surface.
■After removing a hard drive, CD-ROM drive, or a diskette
drive, place it into 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 to liquids.
■If a drive must be mailed, do the following: place the drive
into a bubble pack mailer or other suitable form of protective
packaging; label the package “Fragile: Handle With Care.”
Maintenance and Service Guide4–3

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 dischar ge 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.
It may function normally for a while, then degrade in the internal
layers, reducing its life expectancy.
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-sensitiv e parts in their containers until they
arrive at static-free workstations.
■Place items on a grounded surface before removing them
from their container.
■Always be properly grounded when touching a sensitive
component or assembly.
4–4Maintenance and Service Guide
Page 62
Removal and Replacement Preliminaries
■Place reusable electrostatic-sensitive parts from assemblies in
protective packaging or non-conductive foam.
■Use transporters and conveyers made of antistatic belts and
roller bushings. Ensure that mechanized equipment used for
moving materials is wired to ground, and that proper
materials were selected to avoid static charging. When
grounding is not possible, use an ionizer to dissipate electric
charges.
4.6 Workstation Precautions
Use the following grounding precautions at workstations:
■Cover the workstation with approved static-dissipative
material (refer to Table 4-2).
■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 using fixtures that must directly contact dissipative
surfaces, use fixtures made of static-safe materials only.
■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 them only at
static-free workstations.
■Avoid contact with pins, leads, or circuitry.
■Turn of f power and input signals before inserting or remo ving
connectors or test equipment.
Maintenance and Service Guide4–5
Page 63
Removal and Replacement Preliminaries
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 megaohm ±10% resistance in the ground cords. To
provide proper ground, wear a strap snug against the skin at
all times. On grounded mats with banana-plug connectors,
connect a wrist strap with alligator clips.
■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
them on both feet with a minimum of one-megaohm
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, or sleeve protectors
■Conductive bins and other assembly or soldering aids
■Non-conductive foam
■Conductive tabletop workstations with ground cord of
one-megaohm resistance
■Static-dissipative table or floor mats with hard tie to ground
■Field service kits
■Static awareness labels
■Material-handling packages
