Cables and Connectors

Most cables used throughout the unit are flat, flexible cables. These cables must be
handled with 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 or twisting 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.
CAUTION: When servicing this computer, ensure that cables are placed in their proper location during
the reassembly process. Improper cable placement can damage the computer.
