Removal and Replacement Procedures

Cables and Connectors

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.

Cables

Use the following precautions when handling cables to prevent 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.
