<p>PURPOSE: To provide an information processor to be transitted to power saving operation by an optimum timer value while maintaining balance between usability and power management and a control method for the processor. CONSTITUTION: The information processor is transitted to a power saving mode after the lapse of time set up by a power saving timer from a final user input (or final processing operation), and when a succeeding user input (or a task restart request) is generated at a comparatively early period from the start of the power saving mode, the succeeding power saving timer is reset to a comparatively long period because a user may feel the reduction of operability due to the too short power saving timer. When time from the start of the power saving mode up to the succeeding user input is long, transition to the power saving mode is matched with a user's will, but a power saving effect can be improved by faster transi-tion so that the succeeding power saving timer is reset to a shorter time, thereby transitting the processor to power saving operation by an optimum timer value without being uninten-tionally interrupted.</p> |
