To replace the heat sink and fan assembly, do the following:

1.Remove all media from the drives and turn off all attached devices and the computer. Then, disconnect all power cords from electrical outlets and disconnect all cables that are connected to the computer.

2.Remove the computer cover. See “Removing the computer cover” on page 85.

3.Lay the computer on its side for easier access to the system board.

4.Locate the heat sink and fan assembly. See “Locating major FRUs and CRUs” on page 70.

5.Disconnect the heat sink and fan assembly cable from the microprocessor fan connector on the system board. See “Locating parts on the system board” on page 73.

6.Follow this sequence to remove the four screws that secure the heat sink and fan assembly to the system board:

a.Partially remove screw

b.Partially remove screw

1 , then fully remove screw

3 , then fully remove screw

2 , and then fully remove screw

4 , and then fully remove screw
