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.
