Product Description
The HP Notebook Expansion Base expands the connectivity
of HP Compaq Business Notebook nx9100 Series; HP Pavilion
zd7000, zv5000, and zx5000 Series notebook PCs; and the
Compaq Presario R3000 Series notebook PC. The Expansion
Base provides an efficient, less-cluttered work environment,
improved cable management, and wireless peripherals. It
eliminates the need to purchase a separate monitor, external

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.
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
Ä
the unit.
1–10 Maintenance and Service Guide
Troubleshooting
WARNING: Only authorized technicians trained by HP should repair
Å
this equipment. All troubleshooting and repair procedures are 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.
This chapter contains troubleshooting information for the
HP Notebook Expansion Base. Carefully match the symptoms of
the malfunction against the problem description in the
Troubleshooting tables to avoid a misdiagnosis. Refer to
Chapter 5 for all removal and replacement procedures.
Follow these guidelines when troubleshooting:

3–6 Maintenance and Service Guide
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
■ 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
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 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.
CAUTION: When servicing the Expansion Base, ensure that cables
are placed in their proper locations during the reassembly process.
Ä
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

■ Nonconductive plastic bags, tubes, or boxes
■ Metal tote boxes
