that shipped with your computer and follow the steps in "Before You Begin" on
page 9. For additional safety best practices information, see the Regulatory

Procedure
NOTE: If you install a new processor, a new thermal cooling assembly including an
affixed thermal pad or a new thermal pad along with documentation to illustrate
proper installation is shipped.
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.

perpendicular to the processor when turning the cam screw.
2 Tighten the ZIF socket by turning the cam screw clockwise to secure the processor
module to the system board.
