Removing a PCI Express Card
1. Follow the procedures in Before You Begin .
2. Remove the computer cover (see Removing the Computer Cover ).
3. 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.
4. If your computer includes a card retention mechanism to secure the card in place from the top:
a. Pivot the mechanism upward and gently press the release tab downward to release the mechanism from the two tab slots holding it in place.
b. Set the retention mechanism aside in a secure location.
5. If necessary, disconnect any cables connected to the card. Grasp the card by its top corners, and ease it out of its connector.
6. If you are removing the card permanently, install a filler bracket in the empty card-slot opening.
7. Reseat the card retention mechanism in the tabs and pivot downward to snap it into place.
8. Close the card retention door to snap it into place to secure the card(s).

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.
