Opening and closing the case
Your computer case provides easy access to internal
components.
To remove the side panel:
1 Follow the instructions in “Preventing static electricity
discharge” on page 36.
2 Shut down your computer, then disconnect the power
cord and modem, network, and all peripheral device
cables.
3 Press the power button for ten seconds to drain any
residual power from your computer.
4 Lay the computer down flat, then remove the case cover
thumbscrews from the side panel cover. For the location
of the thumbscrews, see “Back” on page 8.
5 Slide the side panel toward the back of the computer,
then lift it up and away from the computer.
To replace the side panel:
1 Make sure that all of the internal cables are arranged
inside the case so they will not be pinched when you
close the case.
2 Insert the panel tabs into the front of the case, then
swing the side panel toward the back of the computer
to secure it into place.
3 Replace the case cover thumbscrews, then reconnect the
cables and power cord.
Warning
To avoid exposure to dangerous electrical voltages and moving parts, turn
off your computer, then unplug the power cord and modem cable before opening
the case.
Important
Some details of your computer, such as available ports, may differ from
those shown.
Tip
To avoid scratching the case, place it on a towel or other
non-abrasive surface.
