Replacing the microprocessor
Attention:
Do not open your computer or attempt any repair before reading and understanding “Important safety information” on page v.
This section provides instructions on how to replace the microprocessor.
CAUTION:
The heat sink and microprocessor 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 microprocessor, 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 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 42.
4.Locate the system board and disconnect all cables connected to the system board. See “Locating parts on the system board” on page 16.
5.Remove the heat sink to gain access to the microprocessor. See “Replacing the heat sink” on page 50.
Note: Place the heat sink on its side so that the thermal grease on the bottom of it does not get in contact with anything.
