Replacing the system board

Caution

The heat sink has Thermal Interface Material (TIM) on the bottom. Be careful not to damage this material when you remove the heat sink from the processor. If removing the heat sink also pulls the processor out of the processor socket, the processor could be damaged.

6Disconnect the heat sink fan power connector from the system board.

Connector

7Loosen the four captive screws that secure the heat sink to the system board. (Two screws on the far side of the heat sink are not visible in the following photograph.)

Screws

8Remove the heat sink. If the heatsink sticks to the processor, rotate the heatsink slightly to loosen it.

9Lift the processor retention lever, then swing the processor retention bracket out of the way.

10Lift the processor out of the socket and place it in a static-free bag for storage.
