Follow these steps to remove the cover:

Turn off the computer and any peripheral devices connected

to it. Then disconnect the computer’s power cord from the

electrical outlet and from the back panel. Also disconnect

any peripheral device cables that are connected to the

computer, including the keyboard cable.

Turn the computer around so you are facing the back panel.

If necessary, unlock the computer’s cover. (See Chapter 3 for

instructions.)

Loosen the three thumbscrews on the computer’s back panel

by turning them counterclockwise, as shown below. (The

screws will disengage, but they do not come all the way off.)
