CAUTION: Before you begin any of the procedures in this section,

computer and then unplug it from the network jack.

Turn off the computer and devices, and disconnect them from their
electrical outlets.

Pressing the power button when the computer is not connected to an
electrical outlet discharges residual electricity and can help prevent
system board damage.

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.
