Benefits of technology
[0010]An object of the present invention is to improve power management. Another object of the present invention is to allow flexibility in power management.
[0012]Still another object of the present invention is to quickly charge the battery.
[0013]A further object of the present invention is to increase the number of power management modes.
[0014]It is an object of the present invention to provide an apparatus and method for setting a power management mode capable of easily and simply setting the power management mode for a notebook computer system, and automatically setting the power management mode for the notebook computer system as an optimized mode according to the current operating state.
[0015]It is another object of the present invention to provide a charging method for reducing the charge time of a battery by appropriately converting the operating mode of a central processing unit of a Geyserville within the range of less effecting the performance of a computer, if the charging residual amount of a charging battery is judged to be less than a predetermined value when a power mode is converted to an adapter mode from a battery mode.
[0018]Furthermore, while the notebook computer is operated only by the battery, it is operated in a maximum performance mode if the battery residual amount is more than 50% when an AC power source is inputted. On the other hand, if the battery residual amount is less than 50%, the maximum performance mode is switched to a Geyserville cycling mode so as to make the charging speed higher.
Problems solved by technology
Since power management is implemented by only two modes, i.e., the maximum performance mode and battery-optimized mode, according to whether or not AC power detected from the power detector 60 is applied, the power management is not efficiently achieved from an optimized power use point of view.
In addition, in the case where the battery residual amount of the notebook computer is less than 50%, if a AC power source is plugged into the computer while using a battery only as a power source during a work on computer, most of the power is supplied to the system and only a part thereof is supplied to the battery, for thereby making the charging speed slower.

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 ...

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...
