CAUTION: Many repairs may only be done by a certified service technician. You
should only perform troubleshooting and simple repairs as authorized in your
product documentation, or as directed by the online or telephone service and

the product.
1 Using a clean lint-free cloth, remove thermal grease from the heat sink.
2 Apply new thermal grease evenly to the center of the top new processor.
CAUTION: Using excess thermal grease can cause grease to contact the
processor shield, which can cause contamination of the processor socket.
3 Place the heat sink on the processor. Make sure the guide pin is
inserted through the slot of the heat sink. See Figure 3-8.
4 Using a Phillips screwdriver, tighten the two heat-sink retention screws.
5 Replace the system-board assembly. See "Installing a System-Board
Assembly" on page 88.
