Information processing apparatus and power saving effect display method
First Claim
1. An information processing apparatus comprising:
- a power supply module configured to generate a system power to be supplied to the information processing apparatus in either of a first mode and a second mode, the power supply module generating the system power from an externally-supplied utility power in the first mode, the power supply module generating the system power from a power received from a built-in battery in the second mode;
a history storage module configured to cumulatively store;
an imaginary-saved power calculated based on a difference between a reference power usage and a current power usage;
a power generation mode of the power supply module in correlation with the imaginary-saved power, the power generation mode being the first mode or the second mode; and
a date and time at which the imaginary-saved power and the power generation mode are obtained;
the history storage module further storing a first target power savings amount set for the first mode and a second target power savings amount set for the second mode;
a sum module configured to calculate;
a first power savings amount by adding values of the imaginary-saved power correlated with the first mode within a given period; and
a second power savings amount by adding values of the imaginary-saved power correlated with the second mode within the given period; and
a subtraction module configured to calculate;
a first remaining power savings amount by subtracting the first power savings amount from the first target power savings amount; and
a second remaining power savings amount by subtracting the second power savings amount from the second target power savings amount;
an image generator configured to generate an image indicating a degree of power saving attainment for each of the first mode and the second mode on a display device based on the first and second remaining power savings amounts.

Abstract
According to an aspect of the present invention, there is provided an information processing apparatus that is operable in a first operation state and a second operation state, the apparatus including: a history storage unit configured to accumulate: a power usage reduction that is calculated based on a power usage difference between the first operation state and the second operation state; and an acquisition time at which the power usage reduction is acquired; an adding-up unit configured to add up values of the power usage reduction for a given period thereby calculating a power usage reduction amount; and an image generation unit configured to generate an image indicating a difference between the power usage reduction amount and a target value therefor and to display the image on a display device.
