Replacing the Computer Cover
CAUTION: Before you begin any of the procedures in this section,
follow the safety instructions on page 7.
NOTICE: To disconnect a network cable, first unplug the cable from your
computer and then unplug it from the network jack.
1 Turn off the computer and devices, and disconnect them from their
electrical outlets.
2 Briefly press the power button.
Pressing the power button when the computer is not connected to an
electrical outlet discharges residual electricity and can help prevent
system board damage.
3 Make sure that all cables are connected. Fold cables out of the way.
4 Make sure that no tools or extra parts (like screws) are left inside the
computer.
5 From the back of the computer, slide the cover forward until it locks
into place.
6 Tighten the thumbscrew on the back of the computer (see page 42).
