Removing the old processor
1. Turn off the computer and unplug all power cords.
2. Take suitable anti-static precautions and remove the system
unit cover.
If you are unfamiliar with the recommended anti-static
precautions or the procedure for removing the system unit
cover, refer to Appendix A, “Inside the System Unit”.
3. Remove any expansion cards that could restrict access to the
processor socket: disconnect any cables connected to the cards,
remove the screws that secure the cards to the rear of the
system unit, then remove the cards from the system unit.
4. If the computer was turned on immediately prior to
commencing this procedure, wait for at least 15 minutes for
the processor to cool down before proceeding.
Warning
The processor and its attached heat sink can get very hot. You may
burn your fingers if you attempt to remove the processor before it
has cooled down. Also, the processor’s pins expand slightly when
hot and this can prevent it being removed from the socket.
5. Use the illustration at the start of this chapter to locate the ZIF
socket containing the processor.
The heat sink is held onto the top of the processor by a metal
clip that hooks onto the processor socket.
6. Carefully remove the clip from the heat sink.
A lever attached to the socket secures the processor in place.
7. Lift the lever from the locked position until it is upright (at
right-angles to the motherboard). There may be a little
stiffness at the beginning and end of the lever’s movement; be
careful not to use excessive force.
