An information processing apparatus including a push switch turns off a power supply state of a main body and starts shutdown processing when a first user's operation is performed on the push switch in a normal state of the apparatus. When a second user's operation is performed on the push switch during the shutdown processing, the power supply state of the main body is switched between on and off. If the power supply state of the main body is the on state when the shutdown processing is completed, first processing for restarting the main body is performed, and if the power supply state of the main body is the off state when the shutdown processing is completed, second processing for stopping power supply to the main body is performed.

Information processing apparatus including push switch, power supply control method therefor, and storage medium

An information processing apparatus includes a plurality of processing modules that are connected to each other on a ring bus, a connector for optionally attaching to an extension processing unit, a detection unit configured to detect attachment of the extension processing unit to the connector, and a bus switching unit configured to change, in a case where the detection unit detects the attachment of the extension processing unit, a path of the ring bus in such a manner that an extension processing module in the extension processing unit is connected.

Information processing apparatus, control method for information processing apparatus, and storage medium

There is provided a power feeding apparatus including a remaining battery level reception unit configured to receive a remaining battery level of a respective secondary battery included in a respective power receiving apparatus among a plurality of power receiving apparatuses from the respective power receiving apparatuses, a power feeding time determination unit configured to determine power feeding time for the power receiving apparatuses based on the remaining battery level, and a power feeding unit configured to wirelessly feed power to the power receiving apparatuses for the power feeding time.

Power feeding apparatus, power feeding method, and storage medium

A power supply apparatus includes a charging mode information receiving unit configured to receive, from each of a plurality of power receiving apparatuses each including a secondary battery, charging mode information indicating whether each of the power receiving apparatuses requests normal charging of the secondary battery or fast charging of the secondary battery, wherein the fast charging charges faster than the normal charging, a power supply order determination unit configured to determine a power supply order of the power receiving apparatuses based on the charging mode information, and a power supply unit configured to wirelessly supply power to the power receiving apparatuses in the order determined by the power supply order determination unit.

Power supply apparatus, image forming apparatus, power supply method, and storage medium

An apparatus includes an acquisition unit configured to acquire a plurality of pieces of information from a medium, a deletion unit configured to delete a second oldest piece of information, which is next to an oldest piece of information, from the plurality of pieces of information acquired by the acquisition unit, an addition unit configured to add new information to the plurality of pieces of information from which the second oldest piece of information has been deleted by the deletion unit, and a printing unit configured to print on a new medium the plurality of pieces of information resulting from the addition by the addition unit.

Apparatus handling codes, method for controlling the same, and program

An image forming apparatus having a first power state and a second power state in which power consumption is lower than in the first power state includes a detection unit configured to detect an object present in a vicinity of the image forming apparatus, an receiving unit configured to receive a user's operation, a control unit configured to, if the object is detected by the detection unit or if the receiving unit receives the user's operation, shift the image forming apparatus from the second power state to the first power state, and a display unit configured to, if the image forming apparatus is shifted from the second power state to the first power state in response to receipt of the user's operation by the receiving unit, display information indicating that there is dust adhering to the detection unit.

Image forming apparatus, and method for controlling image forming apparatus

An image processing apparatus has a plurality of functions and is adapted to make one or more functions operable by activating programs corresponding to functions. The image processing apparatus includes a selection unit adapted to select a function to be enabled in advance to the other functions when power of the image processing apparatus is turned on or when operation of the image processing apparatus is resumed from a low-power standby state, and a control unit adapted to perform control such that a program corresponding to the function selected by the selection unit is made executable in advance to the other programs.

Image processing apparatus and method of starting image processing apparatus

A data processing apparatus secures data from third parties in event of power loss by utilizing a backup power supply to provide power while data is erased from memory. The data is stored in a nonvolatile memory. A first voltage supply unit supplies voltage to the memory, and a second voltage unit supplies voltage to the memory when the first voltage supply unit is incapable of supplying voltage to the memory. When the first voltage supply unit becomes incapable of supplying voltage to the memory, the memory is controlled to erase the data stored therein using a selected one of a plurality of erasing processes depending on the status of processing of the data.
