NOTICE:
To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface (such
as a connector on the back of the computer).
NOTICE:
To prevent intermittent contact between the ZIF-socket cam screw and the processor when removing or replacing the processor, press to

NOTICE:
To ensure maximum cooling for the processor, do not touch the heat transfer areas on the processor heat sink. The oils in your skin can
reduce the heat transfer capability of the thermal pads.
NOTICE:
When removing the processor, pull it straight up. Be careful not to bend the pins on the processor.
NOTICE:
Ensure that the cam lock is in the fully open position before seating the processor. Seating the processor properly in the ZIF socket does not
require force.
NOTICE:
A processor that is not properly seated can result in an intermittent connection or permanent damage to the processor and the ZIF socket.
