Replacing the Processor Module
1. Align the pin-1 corner of the processor module with the pin-1 corner of the ZIF socket, and insert the processor module.
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.
3. Replace the thermal-cooling assembly (see Replacing the Thermal-Cooling Assembly).
4. Replace in reverse order the remaining components that you removed in Removing the Processor Module, beginning with step5.

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.
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.
NOTE: When you replace the thermal-cooling assembly, be sure to place a new thermal pad on the thermal-cooling assembly such that the pad fits
between the assembly and the processor. You can place the new thermal pad directly on any existing thermal pad already installed on the thermal-
cooling assembly. It is not necessary to remove an existing pad or to clean the surface.
NOTE: When replacing the thermal-cooling assembly, hold up the mylar flap on the assembly so that the flap rests on top of the fan when the thermal-
cooling assembly is in place.
