204 Adding and Replacing Parts
Replacing the Processor Module
NOTICE: Ensure that the cam lock is in the fully open position before seating the
processor module. Seating the processor module properly in the ZIF socket does
not require force.
NOTICE: A processor module that is not properly seated can result in an
intermittent connection or permanent damage to the processor and ZIF socket.
1
Align the pin-1 corner of the processor module with the pin-1 corner of the
ZIF socket, and insert the processor module.
NOTE: The pin-1 corner of the processor module has a triangle that aligns with the
triangle on the pin-1 corner of the ZIF socket.
NOTICE: You must position the processor module correctly in the ZIF socket to
avoid permanent damage to the module and the socket.
When the processor module is correctly seated, all four corners are aligned
at the same height. If one or more corners of the module are higher than
the others, the module is not seated correctly.
2
Tighten the ZIF socket by turning the cam screw clockwise to secure the
processor module to the system board.
NOTE: When you replace the processor thermal-cooling assembly, be sure to
place a new thermal pad on the part of the thermal-cooling assembly that covers
the processor.
3
Replace the processor thermal-cooling assembly (see "Replacing the
Processor Thermal-Cooling Assembly" on page201).
