Abstract:
1. An electronic device including a plurality of electronic components, the electronic device comprising: a power switching unit for outputting a power switching signal based on selective manipulation; a first power input unit for receiving a first power from one of a plurality of external power devices; a second power input unit for receiving a second power from one of the plurality of external power devices; a power converting unit for converting the first power received through the first power input unit into a driving power comprising a voltage level to drive the plurality of electronic components, and for supplying the driving power to the plurality of electronic components; and a power management unit for selectively controlling the power converting unit, wherein the power management unit enables the power converting unit when the second power is input through the second power input unit, and wherein the power management unit controls whether the power converting unit is enabled corresponding to the power switching signal from the power switching unit based on the selective manipulation, when the second power is not input through the second power input unit.
