4.2 Service Considerations

Listed below are some of the considerations that you should keep in mind during the disassembly and assembly of the Compaq Expansion Base.

Tool and Software Requirements

The following tools are needed to service the Compaq Expansion Base:

■Phillips screwdriver (for bezel cage removal)

■Torx T-10 screwdriver (for tray, top cover, left speaker, control bay, control panel, and mechanism assembly removal procedures)

■Torx T-15 screwdriver (for PCI expansion board installation procedures and power supply and backplane removal procedures)

■Phillips screwdriver (for bezel cage removal and installation procedures)

Screws

The screws used in the Compaq Expansion Base are not interchangeable. 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.

CAUTION: When servicing the Compaq Expansion Base, ensure that all screws are kept with the part with which they belong. Using an improper screw during reassembly can damage the Compaq Expansion Base.

IMPORTANT: As each subassembly is removed from the Compaq Expansion Base, it should be placed away from the work area to prevent damage.
