CHAPTER 3: Upgrading Your Computer

4Slide the new card into an available card slot at a 30° angle, then press it down until the holes in the card line up with the screw holes in the case.

5Secure the card to the case using the two screws you removed previously (if you are replacing a card) or the two screws provided with the new card.

6If the new card is a wireless networking card, attach the antenna cables to the appropriate antenna connectors on the card. For a card with three connectors, the black cable should attach to the connector on the right, the blue cable in the middle, and the gray cable on the left.

7Close the back panel by following the instructions in “Opening and closing the case” on page 46.

8Return your computer to its upright position, then reconnect all cables.
