Installing Upgrade Processors
The system board is equipped with a 321-pin Zero Insertion
Force (ZIF) socket at location U11 of the system board. Refer to
the “Board Layout” section in this chapter for the location of the
ZIF socket. This socket is designed for easy removal of an old
processor and easy insertion of an upgrade processor. The ZIF
socket allows you to carefully place the new processor into its
position. If you need to apply excessive force to insert the
processor, you are not installing the processor correctly.
Warning:
Open the socket only if you are actually installing a processor.
The warranty on the original processor will be voided if the S/N
seal is broken. Before proceeding with the upgrade, take note of
the following. The microprocessor and heatsink may be hot if the
system has been running. To avoid the possibility of a burn,
power the system off and let the processor and heatsink cool for
20 minutes.
The 321-pin ZIF socket consists of five rows of pin holes on each
side. 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. If you cannot easily
insert the processor, verify that pin 1 of the processor is aligned
with pin 1 of the socket. Also verify that all the pins are straight, and
not bent nor broken.
