Service Considerations

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

Tool and Software Requirements

To service the computer, you need the following:

Compaq screwdriver kit (Spare Part No. 161946-001)

Torx T-9 screwdriver

5mm nut drivers (for screwlocks and standoffs)

Small, standard screwdriver

Small, Phillips screwdriver

Plastic shroud

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.

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