Patent number: 10467167Abstract: Diodes allow passage of electricity from a battery or a commercial power supply toward a processing system. A power feed reception terminal establishes a connection with a power feed reception path laid in a docking station or with a power feed reception path laid in another external device. Switches either cut off or connect paths meant for connecting the output sides of the diodes and the power feed reception terminal. A magnetic sensor detects the start of a connection between the power feed reception terminal and the power feed reception path laid in the docking station. When the start of a connection is detected, the control unit switches the switches to allow connection. When the power feed reception terminal is connected to the power feed reception path laid in the other external device, the control unit controls the switches based on the result of communication with the other external device.Type: GrantFiled: November 22, 2016Date of Patent: November 5, 2019Assignee: Fujitsu Client Computing LimitedInventor: Hirotaka Yakame
