To remove the microprocessor/heat sink assembly, follow these steps:

1.Remove the microprocessor securing clip from the microprocessor/heat sink assembly.

WARNING: The microprocessor chip can get extremely hot during system operations. Be sure the chip has had sufficient time to cool before touching it.

Press down on the folded part of the clip with a small screwdriver to release the clip.

2.Push outward and then upward on the microprocessor release lever to rotate the lever to its fully vertical position.

3.Lift the microprocessor/heat sink assembly out of its socket (see Figure 4-22).

To install the replacement microprocessor/heat sink assembly, ensure that the microprocessor release lever is in its fully vertical position to allow the micro- processor pins to easily slip into the socket. When the microprocessor/heat sink assembly is in place, rotate the microprocessor release lever to its horizontal position. Hook the microprocessor securing clip over the socket tab nearest the front of the system board, and then snap it over the tab on the back of the socket.

NOTE: Pin 1 on the microprocessor is located on the corner with the largest bevel. The pin-1 hole in the microprocessor socket is located on the corner where the holes are in a diagonal pattern.
