Abstract
A information processing system which enters power management mode when a predetermined time has elapsed since a last user input (or a last processing operation), adjusts the predetermined time according to the action of the operator in response to entering the power mode. If the user transfers back to normal mode quickly the predetermined reference time is increased. If the user responds only after a delay period the predetermined reference time is decreased. By so adjusting the predetermined time a better balance is achieved between energy saving and user convenience for a current level of operator attention to the computer.
