Case Access 3
Opening the Case
To perform work in the internal components of the computer, you must
open the case, which has two removable parts:
•
A chassis cover, that surrounds the sides and top of the system
•
A front faceplate (bezel) that covers the front of the system
Because the components inside your computer are extremely sensitive to
static electricity, be sure to follow the precautions for avoiding static
electricity damage at the beginning of this chapter.
1.
Turn off the computer and disconnect all power cords.
2.
Remove the thumbscrew or lock on the back of the case.
3.
Locate the latches at the rear sides of the case, and pull both latches
out until they clear the chassis.
To remove the chassis cover
Important!
Only qualified personnel
should open the system for
maintenance. You need a
grounding wrist strap and
the proper tools to remove
the computer’s cover.
Warning!
To avoid exposure to
dangerous electrical
voltages and moving parts,
turn off your computer and
unplug the power cord
before removing the system
cover.
