NOTE: If a new processor module is installed, you will receive a new processor heat-
sink assembly, which will include an affixed thermal pad, or you will receive a new
thermal pad along with documentation to illustrate proper installation.
Procedure
1 Align the pin-1 corner of the processor module with the pin-1 corner of the ZIF socket,
then place 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.

module to the system board.
