Opening the case
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.
To remove the left side cover panel:
1
Turn off the computer and disconnect all power cords.
2
Remove the thumbscrews from the back of the side panel and unlock
the chassis lock (if applicable).
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.
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.
