ABSTRACT:
A wire/wireless keyboard and a control method therefor. The keyboard can be used as a wire keyboard if a main body connecting section of the keyboard is connected to a computer body, and the keyboard can be used as a wireless keyboard if the main body connecting section of the keyboard is disconnected from the computer body. The connection status between the computer body and the main body connecting section of the keyboard is automatically judged. If it is judged that they are connected, then the power of the computer body is selected, and the wire mode is executed. On the other hand, if it is judged that they are disconnected from each other, then the internal battery is selected to supply the power from the battery, and the wireless mode is executed. Therefore, the keyboard can be used as both a wire keyboard and as a wireless keyboard. Particularly, under a wireless mode, only if there is a key inputting, the control section is waken up, and therefore, the consumption of the battery power can be minimized.
