Claim Text:
1. An apparatus to control power of an electronic device, the apparatus comprising: a local area network (LAN) controller to control network communication of the electronic device; a communication interface connected to the LAN controller, wherein a connection detector to detect, in response to the external dongle connected to the communication interface, the first generated connection signal transmitted by the signal transformer of the external dongle to establish connection with the LAN controller through the communication interface; and a power controller to supply power to the LAN controller in response to a detection by the connection detector of the first generated connection signal transmitted by the signal transformer of the external dongle and to shut off power to the LAN controller in response to not detecting by the connection detector the first generated connection signal, to thereby by the power controller supply and shut off power to the LAN controller in response to the detection or the not detection by the connection detector of the first generated connection signal transmitted by the signal transformer of the external dongle, wherein the connection detector transmits a low signal to the power controller when the first generated connection signal transmitted by the signal transformer of the external dongle is detected by the connection detector and transmits a high signal to the power controller when the first generated connection signal is not detected by the connection detector.
