Removing, Installing, and Replacing Components
41
Covering an Open I/O Slot
Slot covers prevent air from escaping through the empty hole. If air
escapes, the components inside the computer cannot be properly cooled.
This may damage some components, especially the main processor
(which generates the most heat).
1
Slide the tip of the slot cover (removed earlier) between the chassis
and system board.
2
Push the slot cover down until it rests firmly on the lip in the chassis.
All add-in card brackets and slot covers rest on this lip.
3
Replace the screw (removed earlier) to secure the I/O slot cover.
!
Before opening the system unit, save and close all open files, exit all open
applications, turn off the power to all attached peripheral devices, shut
down the computer, and unplug the power cord.
