Upgrading the processor
The ZIF (zero insertion force) processor socket on the motherboard
is designed to accept a variety of Intel Pentium processors with
processor speeds from 75 to 166 megahertz (MHz). You can
upgrade your processor by replacing it with one of higher
performance.
Removing the old processor
To remove the existing 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 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.
