NOTE: If you are installing just one processor, it must be installed in socket CPU1.
NOTE: You must remove a processor to upgrade a processor or replace a faulty processor.
1. Ensure that you read the Safety instructions.
2. Keep the #2 Phillips screwdriver ready.
3. Follow the procedure listed in Before working inside your system.
4. Remove the processor or processor blank/DIMM blank.
Steps
1. Unlatch and rotate the socket-release levers 90 degrees upward and ensure that the socket-release
lever is fully open.
2. Hold the tab on the processor shield and rotate the shield upward and out of the way.
NOTE: It is recommended that you install/remove the socket protective cap from the processor
shield with the processor shield in the open position.
3. If installed, remove the socket protective cap from the processor shield. To remove the socket
protective cap, push the cap from the inside of the processor shield and move it away from the
socket pins.
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.
4. Install the processor in the socket:
a. Identify the pin-1 corner of the processor by locating the tiny gold triangle on one corner of the
processor. Place this corner in the same corner of the ZIF socket identified by a corresponding
triangle on the system board.
b. Align the pin-1 corner of the processor with the pin-1 corner of the system board.
c. Set the processor lightly in the socket.
Because the system uses a ZIF processor socket, do not use force. When the processor is
positioned correctly, it drops down into the socket with minimal pressure.
d. Close the processor shield.
e. Rotate the socket-release lever 1 and lever 2 simultaneously until it is locked in position.
5. To install the heat sink:
a. If applicable, remove the existing thermal grease from the heat sink using a clean lint-free cloth.
b. Apply thermal grease on the top of the processor. Use the thermal-grease syringe included with
your processor kit to apply the grease in a thin spiral on the top of the processor as shown in the
figure.
CAUTION: Applying too much thermal grease can result in excess grease coming in
contact with and contaminating the processor socket.
