Abstract: A docking system according to the present invention comprises a first detecting means 13 for detecting combination states of a personal computer 2 and a station 1, a second detecting means 14 for detecting separating operation of the personal computer 2 from the station1, a combination holding means for holding a combination state of the personal computer side connector 33 and the station side connector 12, a switching means 32 for switching the personal computer side electric power source portion 39 to the station side electric power source portion 18, a third detecting means 34 for detecting a state of placement of the personal computer 2 on the station 1, and a control unit which cuts the personal computer side electric power source 39 after performing backup processing of an execution program when the personal computer side electric power source portion 39 is in a conductive state when the third detecting means detects a state of placement, supplies electric power from the station side electric power sour

Abstract: A docking system comprising a first detecting element 13 which detects combination states of a personal computer 2 and a station 1. A second detecting element 14 is provided which detects a separation of the personal computer 2 from the station 1. The docking system also includes a combination holding element for holding a combination state of the personal computer side connector 33 and the station side connector 12. Furthermore, the docking system includes a switching element 32 for switching the personal computer side electric power source 39 to the station side electric power source 18. A third detecting element 34 is provided which detects placement of the personal computer 2 on the station 1. A control unit is provided which has three functions. First, it cuts the personal computer side electric power source 39 after performing backup processing of an execution program under a first set of predetermined conditions.
