Claim Text:
1. A method comprising: measuring an average power consumption of a computer for each of a plurality of observation times over a specified time period, wherein a timer for the specified time period is activated in response to a power consumption of the computer being less than a threshold power consumption; causing the computer to determine whether a changeover condition has occurred by comparing the average power consumption of the computer for each observation time with a first reference value and a second reference value, the second reference value being less than the first reference value; changing over to a power-saving state from a power-on state when the changeover condition is determined to have occurred in response to the average power consumption of the computer for an observation time being less than the first reference value and larger than the second reference value; and changing over to a power consumption state that allows the computer to resume within a period of time in response to the average power consumption of the computer for an observation time being less than the second reference value.
