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 bending,
twisting, or tearing the cables, and ensure that they are placed in such a way that they cannot be
caught or snagged by parts being removed or replaced.
CAUTION: When servicing these computers, ensure that cables
are placed in their proper location during the reassembly process.
Improper cable placement can cause severe damage to the unit.
