A power state controlling method is provided that balances quick resumption with reduction of power consumption. An upper limit value Pih and a lower limit value Pil of a power idle state are set for the magnitude of power consumption of a system. The power consumption of the system in a power-on state is calculated. The system changes over to a suspended state when a predetermined time elapses after the system changes over to the power idle state with the lowering of the power consumption. |
