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. NOTE: When installing a new microprocessor module, use the thermal cooling assembly or thermal pad that came with the module, if applicable. 1. Follow the instructions in Before You Begin. NOTICE: Handle the microprocessor module with care. Hold the microprocessor module by its edges and do not touch the processor die (the small chip in the center of the module). 2. Follow the instructions in Removing the Microprocessor 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. 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. 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. 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. 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 tighten the ZIF-socket cam lock and secure the microprocessor module to the system board, use a small, flat-blade screwdriver and rotate the ZIF- socket cam screw clockwise until it comes to the cam stop. 5. Replace the microprocessor thermal-cooling assembly (see Replacing the Microprocessor ThermalCooling Assembly). 6. Replace the microprocessor module cover. 7. Update the BIOS using a flash BIOS update program floppy disk or CD. For instructions on how to flash the BIOS, see Flashing the BIOS.
