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 (Spare Part No. 161946-001)

●

Torx T-9 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.

IMPORTANT:

As each subassembly is removed from the computer, it should be

placed away from the work area to prevent damage.
