Removing the Microprocessor Module
1. Follow the instructions in Preparing to Work Inside the Computer.
2. Loosen the three captive screws securing the microprocessor module cover, then remove the cover and set it aside.
3. Remove the microprocessor thermal-cooling assembly (see Removing the Microprocessor Thermal- Cooling Assembly).
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.
CAUTION: Before you perform any of the procedures in this section, follow the safety instructions in the Product Information Guide.
NOTICE: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface (such as the
back panel) on the computer.
NOTICE: Handle the microsprocessor module with care. Hold the microsprocessor module by its edges and do not touch the processor die (the small chip in
the center of the module).

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.
NOTICE: To avoid damaging the microprocessor, hold the screwdriver so that it is perpendicular to the microprocessor module when turning the cam screw.
NOTE: The ZIF-socket cam screw secures the microprocessor module to the system board.
