Abstract: A computer system to charge a rechargeable battery of an external device regardless of power on/off of the computer system when the external device having the rechargeable battery is connected, and a control method thereof. The computer system includes a connector having a terminal to which an external device is connected, a power supply to supply power to the connector, and a recognition signal generator to generate a predetermined recognition signal to initiate charging a rechargeable battery of the external device with power supplied from the power supply through the connector when the external device having the rechargeable battery is connected to the connector through the terminal. Thus, it is possible to charge the battery of the external device even when the computer system is powered off.

Abstract: An apparatus and method for adjusting a key range of a keycapless keyboard are provided. The apparatus includes a keyboard, a controller, and a manager. The keyboard is comprised of a touch screen. The controller determines whether revision of a user's input value through the keyboard has occurred. The manager adjusts a key range to avoid a user's input error if revisions with a same pattern have occurred as many times as a predefined number.
