Method and apparatus for managing power of portable information device

Abstract

Provided are a method and apparatus for managing power of a portable information device. The apparatus includes: a display unit displaying a power management mode picture when a wake-up signal is input during a low-power consumption state of the portable information device; and a processing unit setting the portable information device again in the low-power consumption state when a user's input, as a response to the power management mode picture, is not received within a predetermined time after the power management mode picture is output to the display unit. Accordingly, even when a button on the portable information device is accidentally pressed, battery thereof can be prevented from being needlessly consumed.

1 . An apparatus for managing power of a portable information device, the apparatus comprising:
 a touch screen to display a power management mode picture in response to a wake-up signal that is input during a low-power consumption state of the portable information device, the power management mode picture occupying a portion of an image displayed by the touch screen; and   a processing unit to maintain the portable information device in the low-power consumption state unless a user's input in an area of the power management mode picture, as a response to the power management mode picture, is received within a predetermined time after the power management mode picture is output to the touch screen,   wherein the wake-up signal is generated by touching the touch screen or by an alarm signal.   
     
     
         2 . An apparatus for managing power of a portable information device, the apparatus comprising:
 a touch screen to display a power management mode picture when a wake-up signal is input during a low-power consumption state of the portable information device, the power management mode picture occupying a portion of an image displayed by the touch screen; and   a processing unit to set the portable information device in a normal operating state when a user's input in an area of the power management mode picture, as a response to the power management mode picture, is received within a predetermined time after the power management mode picture is output to the touch screen,   wherein the wake-up signal is generated by touching the touch screen or by an alarm signal.   
     
     
         3 . A method for managing power of a portable information device, the apparatus comprising:
 displaying a power management mode picture on a touch screen, in response to a wake-up signal that is input during a low-power consumption state of the portable information device, the power management mode picture occupying a portion of an image displayed by the touch screen; and   maintaining the portable information device in the low-power consumption state unless a user's input in an area of the power management mode picture, as a response to the power management mode picture, is received within a predetermined time after the power management mode picture is output to the touch screen,   wherein the wake-up signal is generated by touching the touch screen or by an alarm signal.   
     
     
         4 . A method for managing power of a portable information device, the apparatus comprising:
 displaying a power management mode picture on a touch screen, when a wake-up signal is input during a low-power consumption state of the portable information device, the power management mode picture occupying a portion of an image displayed by the touch screen; and   setting the portable information device in a normal operating state when a user's input in an area of the power management mode picture, as a response to the power management mode picture, is received within a predetermined time after the power management mode picture is output to the touch screen,   wherein the wake-up signal is generated by touching the touch screen or by an alarm signal.
