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. A processor module that is not properly seated can result in an intermittent connection or permanent damage
to the microprocessor and ZIF socket.
NOTE: If you are installing a new processor, you receive a new thermal-cooling assembly which will include an affixed thermal pad, or you will receive a
new thermal pad along with a tech sheet to illustrate proper installation.
NOTE: This procedure assumes that you have completed the removal procedure first.
1. Align the pin-1 corner of the processor module with the pin-1 corner of the ZIF socket, then 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.
When the processor module is properly 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 properly.
