the CPU must align with pin 1 of the CPU socket.
Important:
Handle the CPU by its edges and avoid touching the pins.
6. Insert the CPU into the socket until it is seated in place. The
CPU will fit in only one orientation and can easily be inserted
without exerting any force. Use a screwdriver to turn the screw
to its lock position.
Important:
Do not force the CPU into the socket. Forcing the CPU into
the socket may bend the pins and damage the CPU.
