<p>Embodiments of an apparatus and method for controlling a power management can reduce power consumption, generate less heat or increase the lifetime of the battery. When the operation mode of the CPU is changed into the deeper sleep mode (C4), an audible noise can be generated by the capacitors of the DC/DC converter, such that the C4 mode has not been used. However, according to embodiments of the invention the C4 mode can be enabled when a prescribed device or prescribed program is detected or when the preset conditions are satisfied.</p> |
