Removing a PCI Card
1 Follow the procedures in "Before You Begin" on page 59.
2 Gently push the release tab on the card retention door from the inside to pivot the door open. Because
the door is captive, it will remain in the open position.
3 If you are removing the card permanently, install a filler bracket in the empty card-slot opening.
NOTE:
Installing filler brackets over empty card-slot openings is necessary to maintain FCC certification of the
computer. The brackets also keep dust and dirt out of your computer.
4 Close the card retention door by snapping it into place to secure the cards.
NOTICE:
To connect a network cable, first plug the cable into the network device and then plug it into the
computer.
5 Replace the computer cover, reconnect the computer and devices to electrical outlets, and then turn
them on.

a Enter system setup (see "System Setup" on page 113), select Audio Controller, and then change
the setting to On.
