4.Remove the air baffle from the microprocessor heat sink 1.

5.Completely loosen the screw in each of the two clamps 2 that secure the microprocessor heat sink.

6.Carefully twist the heat sink to break the grease seal to the microprocessor, then remove the heat sink.

Attention: If your computer has been turned off for a long period of time the thermal grease between the microprocessor heat sink and the microprocessor might not allow them to be separated easily. In this case, turn on your computer for a few minutes and allow the heat from the microprocessor to soften the grease.

7.Take notice of the orientation of the beveled corner on the microprocessor 2. This is important when reinstalling the microprocessor on the system board.

8.Remove the microprocessor from the system board by lifting the small handle 1 on the microprocessor.

v If you are installing a new system board assembly, return to the system board procedure.

vIf you are replacing only the microprocessor, continue to “Replacing the microprocessor” on page 40.
