9. Lift the processor module from the ZIF socket.
Replacing the Processor Module
1. Align the pin-1 corner of the processor module with the pin-1 corner of the ZIF socket, and place the processor module on the 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 Replacing the Processor Thermal-Cooling Assembly).
4. Replace the left hard drive (see Replacing a Hard Drive).
5. Replace the top cover (see Replacing the Top Cover).
6. Replace the cosmetic covers (see Replacing the Cosmetic Covers).
7. Firmly attach the keyboard to the computer and close the display (see Closing the Display).
8. Turn the computer upside down and replace the system battery (see Replacing the System Battery).

NOTICE: Ensure that the cam lock is in the fully open position before seating the processor module. Seating the processor module properly in the ZIF
socket does not require force. A processor module that is not properly seated can result in an intermittent connection or permanent damage to the
processor and ZIF socket.
