1. A docking system having a personal computer provided with a personal computer side connector and a personal computer side electric power source portion and a station provided with a station side connector and a station side electric power source portion, comprising:

  • (a) a first detecting means for detecting combination states of said personal computer and said station;

    (b) a second detecting means for detecting separating operation of said personal computer from said station;

    (c) a combination holding means for holding a combination state of said personal computer side connector and said station side connector;

    (d) a switching means for switching said personal computer side electric power source portion to said station side electric power source portion;

    (e) a third detecting means for detecting a state of placement of said personal computer on said station; and

    (f) a control unit, coupled to the first, second and third detecting means, the combination holding means, and to the switching means, which;

    (1) cuts said personal computer side electric power source after performing backup processing of an execution program when said personal computer side electric power source portion is in a conductive state when said third detecting means detects a state of placement;

    (2) supplies electric power from said station side electric power source portion to said personal computer by means of said switching means when said first detecting means detects a state of said station side connector being combined with said personal computer side connector; and

    (3) cuts the electric power source after performing backup processing of an execution program when said personal computer is in an actuation state when said second detecting means detects separating operation of said personal computer.
