Abstract: A method and apparatus for reducing the consumption of standby power through the detection of the idle state of a system are disclosed herein. The apparatus includes a task information acquisition unit, an idle state detection unit, a power reduction determination unit, and a power reduction performance unit. The task information acquisition unit acquires task information from a scheduler. The idle state detection unit detects whether at least one apparatus enters an idle state based on the task information. The power reduction determination unit determines whether to perform the reduction of power consumption of the at least one apparatus based on at least one of an idle counter and the time elapsed after occurrence. The power reduction performance unit performs low-power mode using an apparatus manager corresponding to the at least one apparatus if it is determined that the reduction of power consumption is to be performed.
