CAUTION: Before working inside your computer, follow the safety instructions shipped with your computer.
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).
Removing the Processor
NOTICE: To prevent intermittent contact between the ZIF-socket cam screw and the processor when removing or replacing the processor, press to apply slight pressure to the center of the processor while turning the cam screw.
NOTICE: To avoid damage to the processor, hold the screwdriver perpendicular to the processor when turning the cam screw.
To loosen the ZIF socket, use a small, flat-blade screwdriver and rotate the
ZIF-socket cam screw counterclockwise until it comes to the cam stop.
The ZIF-socket cam screw secures the processor to the system board. Make a note of the arrow on the ZIF-socket cam screw.

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.
Lift the processor from the ZIF socket.
Replacing 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.
Align the pin-1 corner of the processor so that it points to the triangle on
the ZIF socket, and insert the processor into the ZIF socket.
When the processor is correctly seated, all four corners are aligned at the same height. If one or more corners of the processor are higher than the others, the processor is not seated correctly.
NOTICE: To prevent intermittent contact between the ZIF-socket cam screw and the processor when removing or replacing the processor, press to apply slight pressure to the center of the processor while turning the cam screw.
Tighten the ZIF socket by turning the ZIF-socket cam screw clockwise to
secure the processor to the system board.
Peel the backing off the thermal pad and adhere the thermal pad to the
portion of the processor heat sink that covers the processor.
