Replacing the microprocessor

Attention:

Do not open your computer or attempt any repair before reading and understanding the Chapter 1 “Safety
information” on page 1.

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. Turn off the computer and disconnect all power cords from electrical outlets.

2. Remove the computer cover. See “Removing the computer cover” on page 69.

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

4. Remove the heat sink and fan assembly. See “Replacing the heat sink and fan assembly” on page 88.

Note:

Place the heat sink and fan assembly on its side so that the thermal grease on the bottom of it

does not get in contact with anything.

5. Lift the small handle

and open the retainer

to access the microprocessor

Figure 30. Accessing the microprocessor

6. Lift the microprocessor straight up and out of the microprocessor socket.
