2. Remove the protective cover, tape, or label from the surface of the
microprocessor socket, if any is present.
3. Rotate the release lever on the microprocessor socket to the fully open
position.
Attention: Make sure that the release lever on the microprocessor socket is
in the fully open position before you insert the microprocessor in the socket.
Failure to do so might result in permanent damage to the microprocessor,
microprocessor socket, and system board.
4. Carefully grasp the microprocessor and place the microprocessor into the
microprocessor socket.
Note: To maintain correct orientation between the microprocessor and the
microprocessor socket during installation, observe the following information:
v The microprocessor has two notches that are keyed to two tabs on the
sides of the socket.
v A triangle-shaped indicator on one corner of the microprocessor points to a
45-degree angle on the system board.
v Do not use excessive force when you press the microprocessor into the
socket.
5. Close the microprocessor bracket frame; then, close the microprocessor
retention latch and lock it securely in place.

6. Install the heat sink:
Attention: Do not touch the thermal material on the bottom of the heat sink.
Touching the thermal material will contaminate it. If the thermal material on the
microprocessor or heat sink becomes contaminated, contact your service
technician.
a. Align the screw holes on the heat sink with the holes on the system board.
b. Tighten the screws with a screwdriver, alternating among the screws until
they are tight. If possible, each screw should be rotated two full rotations at
a time. Repeat until the screws are tight. Do not overtighten the screws by
using excessive force.
