Abstract
An apparatus having a power saving mode function and method controlling the power saving mode thereof is provided. A USB connector provides a communication interface with a USB external device by use of a USB cable. A USB controller determines whether a voltage is supplied from the USB external device based on a value of the voltage input from the USB connector. A main controller enters either the power saving mode or a standby mode based on the determination of the USB controller. Accordingly, if the computer is turned off, the apparatus enters the power saving mode before a predetermined time passes, to thus prevent the waste of power.
