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.
