1.6 Design Overview

This 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 expansion board
Mini PCI communications device
Hard drive
Display
Keyboard and TouchPad
Audio
Mobile Intel Pentium 4 Processor-M
Fan
PC Card
Product Description
CAUTION: To properly ventilate the notebook, allow at least a 7.6-cm
Ä
(3-inch) clearance on all sides of the notebook.
The notebook uses an electric fan for ventilation. The fan is controlled by a temperature sensor and is designed to come on automatically when high temperature conditions exist. These conditions can be caused by high external temperatures, heavy system power consumption, certain power management/battery conservation configurations, battery fast charging, and some software applications. Exhaust air is displaced through the ventilation grill located on the notebook rear panel.

Troubleshooting

WARNING: Only authorized technicians trained by HP should
repair this equipment. All troubleshooting and repair procedures are
Å
detailed to allow only subassembly/module-level repair. Because of the complexity of the individual boards and subassemblies, do not attempt to make repairs at the component 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.

2.1 Computer Setup and Diagnostics Utilities

4.1 Tools Required

You will need the following tools to complete the removal and replacement procedures:
Magnetic screwdriver

5.0-mm socket for system board standoffs
Flat-bladed screwdriver
Tool kit (includes connector removal tool, loopback plugs,
and case utility tool)

Preliminaries
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 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

CAUTION: When servicing the notebook, ensure that cables are
placed in their proper locations during the reassembly process.
Ä
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.
4–2 Maintenance and Service Guide
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 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, 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, a 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 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 might not be affected at all and can work perfectly throughout a normal life cycle. Or the device might 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 them
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-shielding 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 only 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
Material-handling packages
Nonconductive plastic bags, tubes, or boxes
