NOTICE: To ensure maximum cooling for the microprocessor, do not touch the heat transfer areas on the microprocessor thermal-cooling assembly. Oils in your skin can reduce the heat transfer capability of the thermal pads.

3. Remove the microprocessor thermal-cooling assembly (see Removing the Microprocessor Thermal- Cooling Assembly).

NOTICE: To avoid damaging the microprocessor, hold the screwdriver so that it is perpendicular to the microprocessor module when turning the cam screw.

4.To loosen the ZIF-socket cam lock, use a small, flat-blade screwdriver to rotate the ZIF-socket cam screw counterclockwise until it comes to the cam stop. NOTE: The ZIF-socket cam screw secures the microprocessor module to the system board.
