Service Considerations

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

Tool and Software Requirements

To service the computer, you need the following:

Compaq screwdriver kit

Torx T-8 screwdriver

3/16-inch and 5mm nut drivers (for screwlocks and standoffs)

Small, standard screwdriver

Small, Phillips screwdriver

Diagnostics software

Screws

The screws used in the computer 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.

Fan and RJ11

The Fan and RJ11 are spared with the base assembly. They are not available separately, and may only be obtained by ordering the entire base assembly. This Maintenance and Service Guide contains no removal and replacement procedures for these components.

As each subassembly is removed from the computer, IMPORTANT: it should be placed away from the work area to

prevent damage.
