Opening the case
Important All references to front, rear, left or right on the computer are based on the computer being in a normal, upright position, as viewed from the front.
To work on the internal components of the computer, you must open the case, which has two removable parts:
■A left side cover panel that permits access to the interior of the case
■A bezel that covers the front of the chassis
Because the components inside your computer are extremely sensitive to static electricity, make sure to follow the precautions at the beginning of this chapter for avoiding static electricity damage. Only qualified personnel should open the system for maintenance. If you feel you are qualified to maintain the system yourself, make sure you are properly grounded before opening the system chassis.
Warning Avoid exposure to dangerous electrical voltages and moving parts, by turning off your computer and unplugging the power cord and modem cable (if installed) before removing the chassis cover.
To remove the left side cover panel:
1Turn off the computer and disconnect all power cords.
2Remove the thumbscrews from the back of the side panel and unlock the chassis lock (if applicable).
