A controller of an information processing device receives a packet via the network interface and performs a process corresponding to the received packet when the information processing device operates in the first power mode. The network interface performs a process of transmitting the received packet to the controller when the information processing device operates in the first power mode, and performs a process of discarding the received packet or the process of transmitting the received packet to the controller when the information processing device operates in the second power mode. The network interface has a storage area in which a discarding determination pattern is stored. The controller performs a process of updating a list of the discarding determination pattern to be stored in the network interface based on determination of whether a process on the received packet in the controller is a discarding process.

An apparatus includes a first control unit configured to shift to at least a first power mode and a second power mode where power saving is greater than that in the first power mode, a detection unit configured to detect a predetermined return factor and output a first signal, a second control unit, which includes a storage unit storing information about input of the first signal, configured to output a second signal based on the stored information, and a third control unit configured to output a third signal for shifting the first control unit from the second power mode to the first power mode based on the second signal. The third control unit sets a predetermined value in the storage unit when the first control unit shifts to the second power mode.

A printing apparatus connectable to an external power supply having outputtable voltage information, including: a printing head performing printing by electric power supplied from the external power supply; a resistor having an electric resistivity based on the printing head; a detector detecting a substantial voltage; and a controller configured to: obtain the voltage information from the external power supply; decide a tentative voltage; request the external power supply to output the tentative voltage; energize the resistor with the tentative voltage; decide the substantial voltage if a voltage corresponding to each of the obtained voltage information is supplied based on a result of the detector during the energizing of the resistor; decide an electric power supply voltage based on the substantial voltage; and request the external power supply to output the electric power supply voltage.

An information processing apparatus includes a power controller configured to perform one of first control, which, in response to the information processing apparatus transitioning from a second power state to a first power state, supplies electric power to a storage device and drives a spindle motor, and second control, which, in response to the information processing apparatus transitioning from the second power state to the first power state, supplies electric power to the storage device without driving the spindle motor, wherein, when the information processing apparatus is in the second power state, the power controller performs the first control based on a state controller receiving a first request signal, and the power controller performs the second control based on the state controller receiving a second request signal different from the first request signal.

An information processing apparatus includes a communication unit, a determination unit, a power mode setting unit, an input process unit, and a registration unit. The communication unit receives a communication packet. The determination unit determines whether the communication packet received by the communication unit in a second power mode of first and the second power modes meets at least one of a plurality of determination conditions included in determination condition information. The second power mode is lower in electric power consumption than the first power mode. The power mode setting unit switches a power mode from the second power mode to the first power mode on the basis of a result of determination performed by the determination unit. The input process unit receives user operation. The registration unit registers the determination conditions in the determination condition information on the basis of the user operation received by the input process unit.

An image-forming apparatus comprising a controller and a communicator, wherein the controller is configured to perform to detect distance information of the image-forming apparatus with respect to a portable terminal device possessed by a user based on communication with the portable terminal device using the communicator, detect, based on the detected distance information, approach or leaving of specific portable terminal devices possessed by at least one or more predetermined users to or from the image-forming apparatus, and change a behavior of the image-forming apparatus when the controller detects the approach or the leaving of the specific portable terminal device to or from the image-forming apparatus.

An image forming apparatus 1 (a) displays a visible code in which network identification information of the image forming apparatus 1 is encoded and a function code corresponding to a function of the image forming apparatus 1, (b) transmits function designation screen data to the portable terminal device 2 connected by using the network identification information, (c) receives a function code input to a function designation screen based on the function designation screen data from the portable terminal device 2 via a network, (d) determines whether the received function code matches the displayed function code or not, (el) transmits operation screen data corresponding to the function code to the portable terminal device 2 via the network when both match, and (e2) does not transmit operation screen data to the portable terminal device 2 when both do not match.

The disclosure describes methods and systems for power saving during an upgrade at a device such as a multi-function device. The device includes one or more modules, wherein each module is having an independent power supply. An application runs on the device to identify whether an upgrade is available at the multi-function device. Then, the application identifies one or more modules requiring the upgrade. Once the modules are identified, upgrade for the one or more identified modules is initiated by continuing to provide power to the identified modules. And power to the remaining modules i.e., modules not requiring any upgrade, is disabled from the start of the upgrade process till completion of the upgrade process in order to save overall power consumption of the device.

According to an embodiment, an image forming apparatus supplies, in a normal mode, electric power to an image forming device, and limits, in a power saving mode, power supplying to the image forming device to be less than that in the normal mode. The image forming apparatus communicates, in the normal mode, with a germicidal lamp apparatus via a communication interface such that the germicidal lamp apparatus generates no germicidal light, and communicates, in the power saving mode, with the germicidal lamp apparatus via the communication interface such that the germicidal lamp apparatus generates germicidal light.

A communication apparatus configured not to execute displaying, based on the operation in the connection setting state being started, a screen for receiving an operation for stopping the operation in the connection setting state on a display unit of the communication apparatus.
