Embodiment Construction

[0033]FIG. 2 illustrates the construction of a notebook system according to an apparatus for setting a power management mode of the present invention. FIG. 2 is somewhat similar to FIG. 1, but further includes: a thermal monitor 70 for detecting the temperature of a predetermined position on a PCB of a computer main board; a flash memory 80 for storing the state of an individual preset condition for setting a power management mode and an appropriate optimized power management mode in connection with each other; and a power mode setting button 90 for manually setting a power management mode by an user. According to the state of the individual preset condition for setting a power management mode and whether or not the user depresses the power mode setting button 90, the function and operation of a controller 41 for automatically or manually setting the power management mode for the notebook system are different from FIG. 1.

[0034]The controller 41 supports power management modes for a ...

Abstract

The present invention supports power management modes which includes (1) a maximum power performance mode, (2) a battery-optimized mode, and (3) a performance / optimization cycling mode for performing the maximum performance mode and the battery-optimized mode alternately within a prescribed period of time. The cycling mode allows flexibility in power management and faster charging of the battery.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an electronic device, and more particularly, a device having an apparatus and method for setting a power management mode.[0003]2. Background of the Related Art[0004]In an electronic device using a battery, such as a notebook computer, power management is important. For notebook computers using a Pentium CPU manufactured by the Intel Corporation, the CPU uses a Geyserville technology, which supports two power management modes, i.e., a high performance mode and a battery-optimized mode.[0005]The notebook computer uses the high performance mode under the environment of AC power source, and uses the battery-optimized mode under the environment of a battery-only power source. In addition, the menu wherein an user can set the default mode in each environment is realized through Power Management applet (WordPad, Graphic Panel, or the like) in control panel programs of Microsoft Windows.[0006]FI...
