Computer system and control method thereof
First Claim
1. A computer system comprising:
- a connector including a terminal to which an external device is connected, the connector comprising;
a power supply line to connect the external device including a rechargeable battery; and
a data signal line to transmit and receive data signals between the external device and the computer system;
a power supply to supply power to the power supply line of the connector, where the power corresponds to a charge current having one of a first level and a second level which is higher than the first level; and
a recognition signal generator to generate a predetermined recognition signal to initiate charging a rechargeable battery of the external device with the power supplied from the power supply corresponding to the charge current of the second level through the power supply line of the connector when the external device is connected to the connector,wherein the generated predetermined recognition signal is outputted through the data signal line, and is different from the data signals in a voltage level.

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.

10. A computer system, comprising:
-
a connector to connect an external device to the computer system, the connector comprising; a power supply line to connect the external device including a rechargeable battery; and a data signal line to transmit and receive data signals between the external device and the computer system; and a switching unit to selectively connect a system unit of the computer system to communicate data with the external device via the data signal line, or a recognition signal generator of the computer system to generate a signal to initiate charging of the rechargeable battery of the external device with a power supplied to the power supply line of the connector, the power corresponding to a charge current having one of a first level and a second level which is higher than the first level, and where the charging of the rechargeable battery is with the power that corresponds to the change current of the second level, and where the generated signal is outputted through the data signal line, and is different from the data signals in a voltage level. - View Dependent Claims (11, 12, 13)
