10.Separate the fan-sink from the processor by twisting the fan- sink from side to side to loosen the grip of the thermal bonding compound, then slide the fan-sink off to one side of the processor.

WARNING

When you remove the fan-sink there will be a residual deposit of thermal bonding compound on the bottom of the fan-sink and the top of the processor. This compound can cause skin irritation and stain clothing. Avoid prolonged or repeated contact with skin. Wash your hands thoroughly with soap and water after handling. Avoid contact with eyes and inhalation of fumes. Do not ingest.

11.If you are replacing a Pentium processor with a Pentium/MMX processor, you must remove the two jumpers from jumper block PL18 (next to the socket). Use the illustration at the start of this chapter to locate this jumper block.

12.Ensure that the securing lever on the ZIF socket is still in the upright position.

13.Take the upgrade processor out of its anti-static packaging. Hold the processor by its edges and avoid touching the metal pins.

◊The processor and the ZIF socket are keyed to ensure that the processor is installed in the correct orientation. (The pin pattern is totally different at one corner.) It will only fit into the socket one way.

14.Place the processor in the socket, making sure that it is correctly aligned and that you do not bend or otherwise damage the pins.

◊If the processor is not big enough to occupy the entire socket it should be positioned centrally.

CAUTION

If the processor is misaligned it will not go into the socket, and any attempt to force it will damage the processor, the socket or both.
