NETWORK-CONNECTABLE DEVICE AND METHOD FOR MANAGING POWER THEREOF
First Claim
1. A network-connectable device configured to communicate with one or more computer-related devices via a network, said network-connectable device comprising:
- a mode selector configured to select a power mode between a first power mode and a second power mode;
a power state switching unit operable on the first power mode and configured to;
turn on power of the network-connectable device when one of the computer-related devices is connected to the network in a state where no computer-related device has been connected to the network; and
shut down the power when no computer-related device is connected to the network; and
a power state maintaining unit operable on the second power mode and configured to maintain the power of the network connectable device in a same state regardless of whether the computer-related devices are connected to or disconnected from the network.

Abstract
A network-connectable device is configured to communicate with one or more computer-related devices via a network. The network-connectable device includes: a mode selector configured to select a power mode between a first power mode and a second power mode; a power state switching unit operable on the first power mode and configured to: turn on power of the network-connectable device when one of the computer-related devices is connected to the network in a state where no computer-related device has been connected to the network; and shut down the power no computer-related device is connected to the network; and a power state maintaining unit operable on the second power mode and configured to maintain the power of the network connectable device in a same state regardless of whether the computer-related devices are connected to or disconnected from the network.

11. A method for managing power of a network-connectable device from a computer-related device connected thereto via a network, the network-connectable device comprising:
- a mode selector configured to select a power mode between a first power mode and a second power mode;
a power state switching unit operable on the first power mode and configured to;
shut down the power of the network-connectable device when the network-connectable device receives a stop command signal; and
turn on the power of the network-connectable device when the network-connectable device receives a start command signal; and
a power state maintaining unit operable on the second power mode and configured to maintain the power of the network connectable device in a same state regardless of whether the computer-related devices are connected with or disconnected from the network-connectable device, said method comprising;determining, in response to a disconnection operation of a computer-related device for a disconnection from the network, whether other computer-related devices are already shut down; transmitting the stop command signal to the network-connectable device via the network when all the other computer-related devices are already shut down as a result of the determination; and transmitting the start command signal to the network-connectable device via the network in response to connection operation of the device for a connection with network.
- a mode selector configured to select a power mode between a first power mode and a second power mode;

12. A power management method for a network-connectable device that is configured to communicate with one or more computer-related devices via a network and comprises a mode selector configured to select a power mode between a first power mode and a second power mode, said method comprising:
-
during the first power mode, turning on power of the network-connectable device based on a status change from a state where no computer-related device is connected with the network to a state where one of the computer-related devices is connected to the network; during the first power mode, shut down the power based on a status change from a state where at least one of the computer-related devices is connected with the network to a state where no computer-related device is connected with the network; and during the second power mode, maintain the power of the network connectable device in a same state regardless of whether the computer-related devices are connected with or disconnected from the network-connectable device.
