Abstract:
1. A power supply controlling apparatus comprising: a first power supply that supplies electric power to a central processing unit in the power supply controlling apparatus and another apparatus other than the power supply controlling apparatus; a second power supply that supplies electric power to the another apparatus without supplying the electric power to the central processing unit even when the first power supply is turned off; a measurement portion that measures electric power information concerning electric power supplied to the another apparatus; a storing control portion that stores the electric power information measured by the measurement portion and measurement time when the electric power information is measured, to a volatile storage, and stores the electric power information and the measurement time stored to the volatile storage, to a nonvolatile storage in desired timing; and a supplement portion that, when the first power supply is turned off and turned on again the central processing unit compares a time when the first power supply is turned on again with a final measurement time in a plurality of pieces of measurement time stored in the nonvolatile storage and determines the time when the first power supply is turned on again is later than the final measurement time, supplements to the volatile storage electric power information and time concerning electric power assumed to be supplied to the another apparatus between the final measurement time and the time when the first power supply is turned on again.
