2. Loosen the two captured screws that secure the heat sink clamps 2. Pivot
the clamps to the side to allow the heat sink 1 to be removed.
3. Remove the heat sink from the microprocessor by gently twisting the heat
sink to break the seal formed by the thermal grease and lifting it straight up.
4. Place the heat sink on a clean work surface.
5. Release the microprocessor 1 from the system board socket by pulling
outward and lifting the small handle 2 on the microprocessor socket to its
maximum vertical position. Carefully lift the microprocessor off the socket.
6. Make sure that the microprocessor socket handle is fully in the vertical
position. Otherwise the microprocessor pins might be damaged when
reinstalling the new microprocessor.
