Cables and Connectors (main page)
Most cables used throughout the unit are ribbon cables. Cables 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 the cables are routed in such a way that they
cannot be caught or snagged by parts being removed or replaced.
Cables
NOTE:
In order to gain access to the cables, you must first remove the Battery
Pack and the Palmrest Cover with Touch Pad. Those steps are covered in the
Removal Sequence listed to the left.
Use the following precautions when handling cables to avoid damage to the cable
or computer:
● Always handle cables by their connectors.
● Avoid bending, twisting, or pulling on the cables.
● Apply minimum required force when seating or unseating the cables from their connectors.
● Place the cables in such a manner that they cannot be caught or snagged by parts being
removed or replaced.
● Handle flex cables with extreme care, they can tear easily.
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.
