The power control apparatus includes a first switch, a second switch, and a control unit for controlling the first and second switch according to powered-on/off state of the terminal. One end of each of the first and second switch is connected in common at a first node connected to the external function key and the other end of the first switch is connected to a first input end of the control unit, and the other end of the second switch and the power key are connected in common via a second node connected to a second input end of the control unit. According to the invention, the external function key (the automatic folder switch for example) as the power key is realized so that the user can power-on the terminal without opening the sub-body even in the powered-off state of the terminal, and the terminal keys can perform their own functions in the powered-off state of the terminal.
