Various embodiments of the present disclosure provide techniques and mechanisms for improving user convenience by displaying the state of a battery of an image forming apparatus in more detail. In a case where the state of the battery is an abnormal state in which the battery is not chargeable, the image forming apparatus displays information indicating that the battery is in the abnormal state and information about a remaining capacity of the battery.

An information processing apparatus includes a control unit, a storage unit configured to store a program to be executed by the control unit, a verification unit configured to read the program from the storage unit and to verify the read program, and a light-emitting unit configured to be changed to a predetermined light-emitting state or to be changed from the predetermined light-emitting state based on a result of the verification of the program by the verification unit.

A power supply controlling apparatus includes a first power supply unit that supplies DC power to a load using power supplied from a commercial power supply, a power detecting unit that detects an input voltage and an input current input from the commercial power supply to the first power supply unit, and a control unit that controls the input current to be a constant current having an upper limit current value in response to the input voltage by controlling DC power supplied to the load from the first power supply unit based on the input voltage and the input current which are detected by the power detecting unit.

An image forming apparatus to which an external apparatus is connected includes an image forming unit configured to form an image, and a power supply device configured to supply power to the image forming apparatus and the external apparatus. In a case where a value of an alternating current voltage input to the power supply device is a first value, the power supply device supplies first power to the external apparatus. In a case where the value of the alternating current voltage is a second value smaller than the first value, the power supply device supplies second power smaller than the first power to the external apparatus.

A mobile device includes a first processor, a second processor having a smaller power consumption than the first processor, and a first battery capable of supplying power to the first processor and the second processor, in which a distance between the first processor and an attachable/detachable second battery that is capable of being attached and detached and that is capable of configured to supplying power to the first processor and the second processor is longer than a distance between the second processor and the second battery.

Provided is an image reading apparatus including: an image reading unit configured to output image data representing an image read from an original; and an image control board configured to acquire the image data by controlling an operation of the image reading unit. When a shading error occurs, the image control board determines a part that has caused the shading error by determining whether or not a power supply voltage is being normally supplied to the image reading unit, determining whether or not a light source is normally emitting light, determining whether or not a memory is normally operating, and determining whether or not data output from the image reading unit is normally stored in the memory.

An information processing apparatus includes a power processor, an interface, a detector that detects at least one of a voltage value and a current value on an electric power line that connects the power processor and the interface, and a controller. The controller transmits warning information to an external device via the interface in a case where a detection value of the detector indicates an abnormal value while electric power is supplied to the external device via the interface.

An image forming apparatus includes a plurality of functions for forming an image, which are implemented by a power supply, a signal output unit, a control circuit, and a load operation unit operating in cooperation with one another. The load operation unit includes a sensor for detecting an abnormality. When the sensor has detected an abnormality, the image forming apparatus identifies a failure portion being a cause of the abnormality by checking failure portions of the power supply and the signal output unit, checking a failure portion of the control circuit when there is no failure portion in the power supply and the signal output unit, and checking a failure portion of the load operation unit when there is no failure portion in the control circuit.

An information processing apparatus includes a control unit, a storage unit configured to store a program to be executed by the control unit, a verification unit configured to read the program from the storage unit and to verify the read program, and a light-emitting unit configured to be changed to a predetermined light-emitting state or to be changed from the predetermined light-emitting state based on a result of the verification of the program by the verification unit.

An information processing apparatus includes a control unit and an operation unit. The control unit is configured to generate image data for image display. The operation unit includes a display unit, and is configured to display a screen on the display unit based on the image data generated by the control unit and to accept user operation. The control unit executes first processing for identifying, based on a state of signal output from the operation unit, whether a malfunction has occurred in one of the control unit and the operation unit. The operation unit executes, independently of the first processing by the control unit, second processing for identifying, based on a state of signal output from the control unit, whether the malfunction has occurred in the control unit or in the operation unit.
