  • Electronic apparatus and power saving control method
    Patent number: 9164571
    Abstract: According to one embodiment, an electronic apparatus includes a first device, a first controller, and a second controller. The first controller transits the apparatus between a working state and a hibernation or stand-by state. The second controller shifts the first device from an ordinary operation mode to a power saving mode when a first condition is established while the apparatus is in the working state. The second controller shifts the first device to the power saving mode without waiting that the first condition is satisfied when the apparatus returns to the working state in which the first device is set to the ordinary operation mode after the apparatus shifted to the hibernation state or to the stand-by state in a state that the first device is in the power saving mode.
