Electronic apparatus and power controlling method
First Claim
1. An electronic apparatus comprising:
- a signal receiver configured to receive an input signal;
a power supply configured to supply power to elements of the electronic apparatus;
a controller configured to control power supplied to the power supply; and
a driving circuit configured to output an ON signal to the power supply in response to the signal receiver receiving a preset frequency signal while the controller is turned off,wherein the power supply is further configured to supply power to the elements of the electronic apparatus in response to the ON signal being received from the driving circuit, andwherein the controller is further configured to output an OFF signal to the power supply in response to the signal receiver not receiving the preset frequency signal within a predetermined period of time.

Abstract
An electronic apparatus and a method of controlling power thereto are disclosed. The electronic apparatus including: a signal receiver configured to receive an input signal; a power supply configured to supply power to elements of the electronic apparatus; a controller configured to controls power supplied to the power supply; and a driving circuit configured to output an ON signal to the power supply in order to supply power to the elements of the electronic apparatus in response to the signal receiver receiving a preset frequency signal while the controller is turned off. Thus, the electronic apparatus is automatically turned on and off by an input signal of a predetermined frequency without a user'"'"'s manipulation of an additional power switch, and thus, a user'"'"'s convenience may be improved.

12. A method of controlling power to an electronic apparatus which comprises a power supply, the power controlling method comprising:
-
receiving an input signal comprising a preset frequency signal by a signal receiver while a controller controlling supply of power to the power supply is turned off; outputting an ON signal to the power supply by a driving circuit in response to the signal receiver receiving the input signal comprising the preset frequency signal; supplying power to elements of the electronic apparatus comprising the controller by the power supply in response to the ON signal being received from the driving circuit; and outputting an OFF signal to the power supply by the controller in response to the preset frequency signal not being received within a predetermined period of time. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
