Cables
Most cables used in the Notebook are ribbon cables.
Cables must be handled with extreme care to avoid damage. Use the following precautions
when handling cables to avoid damage to the cable and the Notebook:
Always handle cables by their connectors.
•
In all cases, avoid bending, twisting, pulling, or tearing cables.
•
Apply only the minimum pressure required to seat or unseat cables from their
•
connectors.
Make sure that cables are routed in such a way 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 a Notebook, make sure that cables are placed in their
