Shut Down and Open Computer
1. Shut down your Power Mac. If the computer has been on for any length of
time, wait a few minutes for it to cool before beginning the installation.
2. Touch a port access cover on the back of the computer (Figure 1) to dis-
charge any potential damaging static electricity.
3. Disconnect the power cable. If you need to move the computer to work to a
different area where you can freely work, disconnect the peripheral cables.
4. Locate the security lock at the back of the computer (Figure 2). If it is not
already pressed in, do so now.
5. With the right side of the case facing you, open your Power Mac by lifting
the release latch and lowering the side panel away from the computer’s case
(Figure 3).
Remove Heatsink
Locate the processor heatsink on the logic board (Figure 4). Grasp one of the clips
securing the heatsink with needle-nose pliers, between the heatsink and processor
card. Pull down and away to unhook one side of the clip from the processor card
(Figure 4). Push the clip away from you to unhook it from the other side. Repeat
these steps with the other clip. Once the clips have been unhooked, gently lift the
heatsink and clips away from the processor and set them aside, but not on the
logic board.
Remove Processor Card
Remove the three screws securing the processor card to the logic board (Figure 5).
Grasping the processor card by its edges, carefully lift it straight up and away from
the logic board.

Support Note: When handling computer products, take care to prevent
components from being damaged by static electricity; avoid working in
carpeted areas. Handle processor upgrade cards only by their edges and avoid
touching connector traces and component pins.
Support Note: To avoid regenerating a static charge in your body, do
not walk around the room until after you finish installing the Encore card
and close the computer.
