2.2.2 Installing a Processor

The system board is equipped with a 321-pin Zero Insertion Force
(ZIF) socket The ZIF socket is designed for easy removal of an old
processor and easy insertion of an upgrade processor. If you need
to apply excessive force to insert the processor, you are not installing
the processor correctly.
1. To raise the handle of the ZIF socket, push it down, slightly pull it
out to the side, then raise it as far as it will go. It may be
necessary to initially apply a small amount of sideways force to
free the handle from its retaining " tab" . Once clear of the " tab" ,
the handle will open relatively easily. The top plate will slide back.
2. Insert the processor until the pins are in their corresponding
holes. Make sure pin 1 of the processor is aligned with pin 1 of
the socket. To prevent improper processor installation, the ZIF
socket has a Plug/Keying mechanism. Several holes in the socket
are plugged so that the processor will go in only one way.
3. Push the handle down until the handle locks into place. The top
plate will slide forward.
Warning:
The processor must be kept cool by using a fan with heatsink.
Otherwise, the processor will overheat and damage the
processor and the system board.
