Product Description

1.4 Design Overview

This section presents a design overview of key parts and features of the HP Notebook Expansion Base. Refer to

Chapter 3,

“Illustrated Parts Catalog,” to identify replacement parts, and

Chapter 5, “Removal and Replacement Procedures,” for

disassembly steps.

The Expansion Base provides the following device connections:

Expansion cable

S/PDIF (Sony/Philips Digital Interface) audio connector

Audio out/Headphone jack

Composite out

RJ-11 (modem) connection (from wall to Expansion Base)

RJ-11 (modem) connection (from Expansion Base to notebook)

RJ-45/Ethernet port

Six USB 2.0 connectors

S-Video out

Serial port

The HP Notebook Expansion Base uses electrical fans for ventilation. The fans are controlled by a temperature sensor and are 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, and software applications. Exhaust air is displaced through the ventilation grill located on the right side, left side, and rear panel of the unit.

Ä CAUTION: To properly ventilate the HP Notebook Expansion Base, allow at least a 7.6-cm (3-inch) clearance on the left and right sides of the unit.

Removal and Replacement

Preliminaries

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

Phillips P0 screwdriver

5.0-mm hex socket for system board standoffs

Flat-bladed screwdriver

Tool kit (includes connector removal tool, loopback plugs, and case utility tool)

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 Expansion Base, place the subassembly (and all accompanying screws) away from the work area to prevent damage.

Maintenance and Service Guide 4–1

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; these cables tear easily.

Ä CAUTION: When servicing the Expansion Base, ensure that cables are placed in their proper locations during the reassembly process.

Improper cable placement can damage the Expansion Base.

4.3 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 cycle. Or the device might function normally for a while, and then degrade in the internal layers, reducing its life expectancy.

4–2 Maintenance and Service Guide

Removal and Replacement Preliminaries

4.4 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 Guide 4–3

Removal and Replacement Preliminaries

4.5 Workstation Precautions

Use 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 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.

4–4 Maintenance and Service Guide

Removal and Replacement Preliminaries

4.6 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.

■ 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
