Abstract
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.
Claims20
An image forming apparatus operable by power supplied from a battery, the image forming apparatus comprising:
- a memory;
- and
- at least one processor in communication with the memory,
- wherein the at least one processor of the image forming apparatus is configured to perform:
- determining a state of the battery;
- (a) in a case where the determined state of the battery corresponds to a state in which the battery is not chargeable but dischargeable, displaying information indicating that the battery is in an abnormal state and information about a remaining capacity of the battery;
- and
- (b) in a case where the determined state of the battery corresponds to a state in which the battery is neither chargeable nor dischargeable, displaying the information indicating that the battery is in the abnormal state and not displaying the information about the remaining capacity of the battery.
A method for controlling an image forming apparatus operable by power supplied from a battery, the method comprising:
- determining a state of the battery;
- (a) in a case where the determined state of the battery corresponds to a state in which the battery is not chargeable but dischargeable, displaying information indicating that the battery is in an abnormal state and information about a remaining capacity of the battery;
- and
- (b) in a case where the determined state of the battery corresponds to a state in which the battery is neither chargeable nor dischargeable, displaying the information indicating that the battery is in the abnormal state and not displaying the information about the remaining capacity of the battery.
A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method for controlling an image forming apparatus operable by power supplied from a battery, the method comprising:
- determining a state of the battery;
- (a) in a case where the determined state of the battery corresponds to a state in which the battery is not chargeable but dischargeable, displaying information indicating that the battery is in an abnormal state and information about a remaining capacity of the battery;
- and
- (b) in a case where the determined state of the battery corresponds to a state in which the battery is neither chargeable nor dischargeable, displaying the information indicating that the battery is in the abnormal state and not displaying the information about the remaining capacity of the battery.
An image forming apparatus operable by power supplied from a battery, the image forming apparatus comprising:
- a memory;
- and
- at least one processor in communication with the memory,
- wherein the at least one processor of the image forming apparatus is configured to perform:
- executing USB charging for charging the battery with power supplied from an electric device via a USB cable,
- wherein the battery is charged with the power supplied from the electric device via the USB cable on a condition that the image forming apparatus shifts to a power saving state in which display processing on a display unit in the image forming apparatus is not executed.
