Abstract
Disclosed is a power management method for portable electronic terminals. According to the present invention, a priority rank is decided in accordance with the user's intention, or on the degree of importance of each functional module, or on the operation time thereof. Therefore, when power is deficient, the modules with lower priorities are not provided with power temporarily, but operation of the modules with higher priorities is guaranteed.
Claims9
A power management method for a portable electronic terminal having at least two modules that perform distinct functions of the terminal, the method comprising the steps of:
- setting a priority for each module;
- calculating a sum of necessary power to turn on the at least two modules under power-saving mode, and measuring a currently available power at intervals of a predetermined cycle;
- comparing the sum of necessary power to turn on the modules with the currently available power;
- and
- if the currently available power is less than the sum of necessary power to turn on all of the modules, allotting the currently available power to at least one module based on the set priority.
