Service considerations
The following sections include some of the considerations that you must keep in mind during disassembly
and assembly procedures.
NOTE: 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
Using excessive force during disassembly and reassembly can damage plastic parts.
Cables and connectors
Handle cables with extreme care to avoid damage.
IMPORTANT: 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.
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 so that they cannot be caught or snagged as you remove or replace parts. Handle flex cables with
extreme care; these cables tear easily.
Drive handling
Note the following guidelines when handling drives.
