Seating the processor module properly in the ZIF socket does not require force. 1. Align the pin-1 corner of the processor module so that it points to the triangle on the ZIF socket, and insert the processor module into the ZIF socket. When the processor module is correctly seated, all four corners are aligned at the same height. If one or more corners of the module are higher than the others, the module is not seated correctly. 2. Tighten the ZIF socket by turning the cam screw clockwise to secure the processor module to the system board. 3. Replace the processor thermal-cooling assembly (see Processor Thermal-Cooling Assembly). 4. Update the BIOS using a flash BIOS-update program CD (see Flashing the BIOS From a CD).
