removing the side panel
You must remove the side panel to add memory, insert add-in cards, install or
remove drives, or change the battery:
1 Turn off the computer and all peripherals.
2 Disconnect the modem/telephone cable.
3 Disconnect the power cord and all other attached cables (such as the
keyboard, mouse, and monitor).
4 Loosen the two thumbscrews on the right side of the back panel. The first
time you loosen these screws you’ll need a flathead screwdriver. (These
screws do not detach; they’ll stay on the side panel loosely until you tighten
them again.)
5 Stand behind the computer, and place one hand on top of the chassis.
