1.8 Design Overview
This section presents a design overview of key parts and features
of the tablet PC. 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 expansion board
■
Hard drive
■
Display
■
Optional keyboard/pointing stick
■
Audio
■
Transmeta processor
Ä
■
Fan
■
PC Card
■
CompactFlash
■
External MultiBay
■
Modem or modem/NIC
The tablet PC 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 left side of the tablet PC.
CAUTION: To properly ventilate the tablet PC, allow at least a
7.6 cm (3-inch) clearance around the sides of the tablet PC.

Removal and Replacement
This chapter provides essential information for proper and safe
removal and replacement service.
4.1 Tools Required
You will need the following tools to complete the removal and
replacement procedures:
■
Magnetic screwdriver
■
Torx T8 screwdriver
4
Preliminaries
■
Phillips P0 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 Considerations
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 tablet PC, place the
✎
Plastic Parts
subassembly (and all accompanying screws) away from the work
area to prevent damage.
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; these cables tear
easily.
CAUTION: When servicing the tablet PC, ensure that cables are
Ä
placed in their proper locations during the reassembly process.
Improper cable placement can damage the tablet PC.

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 tablet PC, damage to a
removable drive, or loss of information, observe the following
precautions:
■
Before removing or inserting a hard drive, shut down the
tablet PC. If you are unsure whether the tablet PC is off or in
Hibernation, turn on the tablet PC, 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.
■
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 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 to 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 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.
4.5 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.
4–4 Maintenance and Service Guide
Removal and Replacement Preliminaries
■
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.
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, only use fixtures made 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.
Maintenance and Service Guide 4–5
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 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,
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
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
■
