4. Remove the CPU enclosure cover. See Removing the CPU Enclosure Cover (Top) on
page 10.
5. Remove the two CPU board screws closest to the adapter board. This allows some
free movement of the CPU board when you remove the adapter board.
6. With both hands, place your thumbs and fingers on each side of the adapter
board. Four plastic tabs on the bottom of the CPU enclosure hold it in place.
Gently pull it up just enough so it is clear of the plastic tabs.
7. Once clear of the plastic tabs, slide it off the CPU board connector and set it aside.
