Abstract

An electronic apparatus including external power sources in different kinds, and a power supplying unit being supplied with power from the external power sources and supplying it as system power, including a source determination unit determining kinds of the external power sources; and a control unit controlling the power supplying unit based on the determination result by the source determination unit so that system power is supplied in a driving mode set in advance correspondingly to the concerned external power source. Thus, the electronic apparatus is capable of improving energy efficiency by changing its own driving state optimally according to the type of an external power source.

Description

technical field [0001] The invention relates to an electronic device. Specifically, it relates to an electronic device capable of improving energy efficiency by optimally changing its own drive state according to the type of external power supply. Background technique [0002] see figure 1 , a brief description of traditional electronic devices. [0003] In general, an electronic device includes an external power source 10 and a main body 100 . The main body 100 includes an internal battery 9 , a connection terminal 30 for receiving power supplied from an external power source 10 , and a user input unit 20 . The main body 100 is driven by using power from the internal battery 9 or from the external power source 10 . The external power source 10 can be classified into an AC adapter 1 and a limited power source 5 . The AC adapter generally converts commercial AC power supplied thereto to DC power and supplies the converted DC power to the main body 100 , whereas the limit...
