4.3 Service Considerations

Listed below are some of the considerations that you should keep in mind during the disassembly and
assembly of the computer.
4.3.1

Tools and Software Requirements

To service the computer, you need the following:
„
Torx T-15 screwdriver
„
Flat-bladed screwdriver
„
Diagnostics software
„
Tool kit, Compaq part number 100767-001 (includes case utility tool, connector removal tool,
and loop-back plugs)
4.3.2

Screws

The screws used in the computer are not interchangeable. They may have standard or metric threads
and may be of different lengths. The standard screws have a silver finish, while the metric screws
have a black finish. If an incorrect screw is used during the reassembly process, it can damage the
unit. Compaq strongly recommends that all screws removed during disassembly be kept with the part
that was removed, then returned to their proper locations.
As each subassembly is removed from the computer, it should be placed away from the
work area to prevent damage.
4.3.3

Cables and Connectors

Most cables used throughout the unit are flat, flexible cables. These cables must be handled with care
to avoid damage. Apply only the tension required to seat or unseat the cables during insertion or
removal from the connector. Handle cables by the connector whenever possible. In all cases, avoid
bending, twisting, or tearing the cables, and ensure that the cables are routed in such a way that they
cannot be caught or snagged by parts being removed or replaced.
CAUTION: When servicing this computer, ensure that cables are placed in their proper location during the
reassembly process. Improper cable placement can damage the computer.
