5. Lift the microprocessor module straight up and out of the ZIF socket.

Replacing the Microprocessor Module



1. Follow the instructions in Preparing to Work Inside the Computer



2. Follow the instructions in Removing the Microprocessor Module.



3. Align the pin-1 corner of the new microprocessor module with the pin-1 corner of the ZIF socket, and insert the microprocessor module.

When the microprocessor module is properly seated, all four corners of the module are aligned at the same height. If one or more corners of the module is higher than

the others, the module is not properly seated.



4. Tighten the ZIF-socket cam lock by turning the cam screw clockwise to secure the microprocessor module to the system board.



5. Replace the microprocessor thermal-cooling assembly (see Replacing the Microprocessor Thermal- Cooling Assembly).

NOTICE: When removing the microprocessor module, pull the module straight up and out of the ZIF socket. Exercise care not to bend the pins on the

microprocessor module.

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: Ensure that the cam lock is in the fully open position before seating the microprocessor module. Seating the microprocessor module properly in the

ZIF socket does not require force. A microprocessor module that is not properly seated can result in an intermittent connection or permanent damage to the

microprocessor and ZIF socket.

NOTE: The pin-1 corner of the microprocessor module has a triangle that aligns with the triangle on the pin-1 corner of the ZIF socket.

NOTE: Gently press down on the substrate on which the processor die is mounted to ensure the microprocessor module is properly seated.

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