CHAPTER 4: Upgrading Your Computer

Replacing the system board

To replace the system board:

1Remove the side panel by following the instructions in “Removing the side panel” on page 31.

2Disconnect any expansion card cables from the cards and from the system board, noting their locations and orientation. (You will reconnect the cables after you reinstall the cards.) You can also mark the cables with tape labels to simplify reconnecting cables later.

3Open the card retention lever.
