Product Description
1.6 Design OverviewThis section presents a design overview of
key parts and features of the notebook. Refer to Chapter 3,
“Illustrated Parts Catalog,” to identify replacement parts, and
Chapter 5, “Removal and Replacement Procedures,” for disassembly
steps.
The system board provides the following device connections:
■ Memory module
■ Mini PCI communications devices
■ Hard drive
■ Display
■ Keyboard and TouchPad
■ Audio
■ Intel Pentium M and Celeron M processors
■ Fan
■ PC Card
ÄCAUTION: To properly ventilate the notebook, allow at least a
7.6-cm (3-inch) clearance on the left and right sides of the
notebook.
The notebook 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 notebook.

level or modifications to any printed wiring board. Improper
repairs can create a safety hazard. Any indication of component
replacement or printed wiring board modification may void any
warranty or exchange allowances.

Preliminaries
This chapter provides essential information for proper and safe
removal and replacement service.
4.1 Tools RequiredYou will need the following tools to complete
the removal and replacement procedures:■ Magnetic screwdriver■
Phillips P0 screwdriver■ Flat-bladed screwdriver■ Tool kit—includes
connector removal tool, loopback plugs,
and case utility tool
Maintenance and Service Guide 4–1
-
Removal and Replacement Preliminaries
4.2 Service ConsiderationsThe 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 notebook, 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
ÄCAUTION: When servicing the notebook, ensure that cables are
placed in their proper locations during the reassembly process.
Improper cable placement can damage the notebook.
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 DrivesRemovable drives are
fragile components that must be handled with care. To prevent
damage to the notebook, damage to a removable drive, or loss of
information, observe the following precautions:■ Before removing or
inserting a hard drive, shut down the
notebook. If you are unsure whether the notebook is off or in
hibernation, turn the notebook 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 Guide 4–3

Removal and Replacement Preliminaries
4.4 Preventing Electrostatic DamageMany 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.
4–4 Maintenance and Service Guide
-
Removal and Replacement Preliminaries
4.5 Packaging and Transporting PrecautionsUse 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 Guide 4–5
-
Removal and Replacement Preliminaries
4.6 Workstation PrecautionsUse the following grounding
precautions at workstations:■ Cover the workstation with approved
static-shielding material
(refer to Table 4-2, “Static-Shielding Materials”).■ 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.
4–6 Maintenance and Service Guide
-
Removal and Replacement Preliminaries
4.7 Grounding Equipment and MethodsGrounding 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.
■ 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
