Replacing the heat sink assembly

Attention:

Do not open your computer or attempt any repair before reading and understanding the

“Important safety information” on page 1

This section provides instructions on how to replace the heat sink assembly.

CAUTION:

The heat sink and fan assembly might be very hot. Turn off the computer and wait three to five
minutes to let the computer cool before removing the computer cover.

To replace the heat sink 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. Place a soft, clean towel or cloth on the desk or other flat surface. Hold the sides of your computer and

gently lay it down so that the screen is against the surface and the cover is facing up.

3. Remove the computer cover. See “Removing the computer cover” on page 75.

4. Locate the heat sink assembly on the system board. See “Locating major FRUs and CRUs” on page 66.

5. Remove the system board shield. See “Removing and reinstalling the system board shield” on page 83.
