Installing the Second Processor

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. Before you begin this procedure, review the safety instructions that came with the system.

1Ensure that you have followed the steps mentioned in "Before You Begin" on page 3.

2Unpack the new processor.

CAUTION: Positioning the processor incorrectly can permanently damage the system board or the processor. Be careful not to bend the pins in the socket.

CAUTION: Do not use force to seat the processor. When the processor is positioned correctly, it engages easily into the socket.

3Align the notches in the processor with the socket keys on the ZIF socket and set the processor lightly in the ZIF socket. See Figure 1-1.

4Close the processor shield.

5Using a clean lint-free cloth, remove the thermal grease from the heat sink.

CAUTION: Applying too much thermal grease can result in excess grease coming in contact with and contaminating the processor socket.

6Open the grease applicator included with your processor kit and apply all of the thermal grease in the applicator to the center of the topside of the new processor.

7Place the heat sink on the processor.

8Tighten the heat-sink retention sockets. See Figure 1-2.
