ABSTRACT:
Disclosed is an information processing system that can operate in at least two modes of power management, a normal mode and a suspend mode. The system can enter the suspend mode in response to the expiration of an inactivity suspend timer and can resume therefrom in response to a resume request. While resuming, the system is operative to measure an elapsed time between entering the suspend mode and resuming therefrom. The system is further operative during the resume to either (1) prompt a user to enter a password if the elapsed time is longer than a predetermined time or (2) skip (1) and not prompt a user to enter a password if the elapsed time is shorter than the predetermined time. The system decreases the amount of time required to resume from a power saving mode by not requiring a password input when a resume request by a user, such as key input, occurs within a relatively short period of time after the system entered the suspend mode.
