socket.
1. Align the pin-1 corner of the processor module with the pin-1 corner of the ZIF socket, and insert the processor module.
NOTE: The pin-1 corner of the processor module has a triangle that aligns with the triangle on the pin-1 corner of the ZIF socket.
NOTICE: You must position the processor module correctly in the ZIF socket to avoid permanent damage to the module and the socket.

others, the module is not seated correctly.
