1. An information processing apparatus, comprising:
- a remaining charge detector to detect charge remaining in a battery;
a status indicator to display status of the battery based on an output of the remaining charge detector;
a controller to control an operating mode of the information processing apparatus and power supply to the status indicator, the operating mode at least including an energy save mode; and
an instruction acceptance unit to accept user instruction for displaying the status of the battery using the status indicator,wherein the controller stops power supply to the status indicator by switching a power supply control signal for the remaining charge detector in transitioning to the energy saving mode, and, while still in the energy saving mode, starts power supply to the status indicator by switching the power supply control signal for the remaining charge detector in response to the instruction acceptance unit accepting the user instruction for displaying and stops power supply to the status indicator by switching the power supply control signal for the remaining charge detector in response to releasing the user instruction for displaying.

Abstract
An information processing apparatus includes a status indicator that displays status of a battery, a controller that controls an operating mode of the information processing apparatus and supplies power to the status indicator, and an instruction acceptance unit that accepts user instruction to display to the status indicator. The controller turns off the status indicator in transitioning to the energy saving mode, and, in the energy saving mode, turns on the status indicator in response to the instruction acceptance unit accepting the user instruction to display and turns off the status indicator in response to the user instruction to display being released.

10. A method of controlling an information processing apparatus, comprising the steps of:
-
displaying, using a status indicator of the information processing apparatus, a remaining charge status of a battery; controlling an operating mode of the information processing apparatus and power supply to the status indicator, the operating mode at least including an energy save mode; accepting user instruction for displaying the status of the battery using the status indicator; stopping power supply to the status indicator in transitioning to the energy saving mode by switching a power supply control signal for the remaining charge detector; starting power supply to the status indicator in response to accepting the user instruction for displaying in the energy saving mode by switching the power supply control signal for the remaining charge detector; and stopping power supply to the status indicator in response to releasing the user instruction for displaying in the energy saving mode by switching the power supply control signal for the remaining charge detector. - View Dependent Claims (11, 12, 13)
