Screws
The screws used in these products are not interchangeable. If an incorrect screw is used during
the reassembly process, it could cause damage to the unit. Compaq strongly recommends that all
screws removed during the disassembly process 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.
Cables and Connectors
Most cables used throughout the unit are ribbon cables. These must be handled with extreme 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
