Service considerations
The following sections include some of the considerations that you must keep in mind during disassembly and
assembly procedures.
✎
As you remove each subassembly from the computer, place the subassembly (and all accompanying screws) away
from the work area to prevent damage.
Plastic parts
Ä
CAUTION:
Using excessive force during disassembly and reassembly can damage plastic parts. Use care when
handling the plastic parts. Apply pressure only at the points designated in the maintenance instructions.
Cables and connectors
Ä
CAUTION:
When servicing the computer, be sure that cables are placed in their proper locations during the
reassembly process. Improper cable placement can damage the computer.
Cables must be handled with extreme care to avoid damage. Apply only the tension required to unseat or seat the
cables during removal and insertion. Handle cables by the connector whenever possible. In all cases, avoid
bending, twisting, or tearing cables. Be 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; these cables tear easily.
