An information processing apparatus includes a processor and a first device. The processor executes an operating system and a power control application, which operates on the operating system and controls a power mode of the information processing apparatus. The first device is connected to the processor to communicate with the processor, and notifies the operating system of a return time. The power control application notifies the first device of information indicating the power mode of the information processing apparatus. Based on the information notified by the power control application, the first device determines a return time of which the operating system is to be notified, and notifies the operating system of the determined return time. Based on the return time notified by the first device, the operating system determines a power saving state to which the processor is to shift, and shifts the processor to the determined power saving state.
