Replacing the microprocessor

This section provides instructions on how to replace the microprocessor.

1. Open the computer cover. See “Opening the cover” on page 84.

2. Locate the microprocessor. See “System board locations” on page 83.

3. Remove the four screws securing the heat sink to the retention module on the

system board and lift the heat sink off the system board.

4. Disengage the microprocessor from the system board socket by pivoting the

small handle upward until it is in the vertical position.

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

Notes:

a. Your microprocessor and socket might look different than the one

illustrated.

b. Note the orientation of the microprocessor in the socket. Look for the small

triangle on one corner of the microprocessor. This is important when

reinstalling the microprocessor on the system board.

c. Do not drop anything onto the microprocessor socket while it is exposed.

The socket pins must be kept as clean as possible.
