1.

Prepare the computer for disassembly (

Preparation for Disassembly on page 159

).

2.

Remove the computer access panel (

Computer Access Panel on page 163

).

3.

Lift the fan up and place it on top of the optical drive to access the front bezel release tabs. You
do not need to disconnect the fan cable from the system board.

4.

Unscrew the four screws that secure the heatsink to the system board, and then lift the heatsink
from the system board.

CAUTION:

Heatsink retaining screws should be removed in diagonally opposite pairs (as in an

X) to even the downward forces on the processor. This is especially important as the pins on the
socket are very fragile and any damage to them may require replacing the system board.
