NOTICE:
Do not touch the processor die. Press and hold the processor down on the substrate on which the
die is mounted while turning the cam screw to prevent intermittent contact between the cam screw and
processor.
NOTICE:
Ensure that the cam lock is in the fully open position before seating the processor module.

not properly seated can result in an intermittent connection or permanent damage to the microprocessor
and ZIF socket.
NOTE:
If a new processor is installed, you will receive a new heatsink 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.
