Method and apparatus for managing power of portable information device
First Claim
1. An apparatus for managing power of a portable information device, the apparatus comprising:
- a display unit 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 display unit; 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 display unit,wherein the wake-up signal is generated when a phone call is received.

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.

6. A method of managing power of a portable information device, the method comprising:
-
placing the portable information device in a suspend state when power of the portable information device falls below a pre-determined threshold; generating a power management mode picture as a predetermined portion of an image displayed on a display and temporarily setting the portable information device in a power management screen saver mode in response to a wake-up signal that is input during the suspend state; and returning the portable information device to the suspend state when a user input, as a response to the power management mode picture, is not received in an area of the power management mode picture within a predetermined time after the power management mode picture is generated, wherein the wake-up signal is generated when a phone call is received. - View Dependent Claims (7)

8. An apparatus for managing power of a portable information device, the apparatus comprising:
-
a complex programmable logic device (CPLD) unit to send an interrupt signal based on whether a battery voltage drops below a predetermined threshold voltage; a processing unit to receive the interrupt signal and to enter a suspend mode; a first general purpose input-output (GPIO) unit to receive the interrupt signal from the CPLD indicating the battery voltage drop being below the predetermined threshold voltage and sending a control signal; a sleep mode setting unit to receive the control signal from the first GPIO unit and to set the portable information device to a low-power consumption mode; an input/output device (I/O) device unit to generate a predetermined wake-up signal; a second GPIO unit to receive and to transmit the wake-up signal; and a power management screen saver mode executing unit to receive the transmitted wake-up signal from the second GPIO unit and to execute a power management screen saver mode while outputting a power management mode picture to a display unit of the I/O device unit, the power management mode picture occupying a predetermined portion of an image displayed on the display unit, wherein the wake-up signal is generated when a phone call is received. - View Dependent Claims (9, 10)
