Microprocessor and Heat Sink Assembly
If the replacement heat sink and microprocessor are separate, peel the thermal-
pad protective cover off the bottom of the heat sink before attaching the heat
sink to the microprocessor.
To install the replacement microprocessor/heat sink assembly, ensure that the
microprocessor-socket release lever is in its fully vertical position to allow the
microprocessor pins to easily slip into the socket. When the microprocessor/
heat sink assembly is in place, rotate the microprocessor-socket release lever to
its horizontal position. Hook the microprocessor securing clip over the socket
tab nearest the right side of the system board, and then snap it over the tab on
the opposite side of the socket.
NOTE: Pin 1 on the microprocessor is located on the corner with the largest
bevel. The pin-1 hole in the microprocessor socket is located on the corner
where the holes are in a diagonal pattern.
