Method and apparatus for setting the reduced power mode of a processing system in accordance with the type of peripherals connected to the processing system

摘要

An information processing system that can return to an operational state at any time as a result of an event input from a peripheral device which is constructed by an information processing system main body and a peripheral device and has a power management function having a plurality of suspension modes is constructed by a connection state detection unit for detecting whether a predetermined peripheral device is connected to the information processing system main body or not, an event detection unit for detecting an event to instruct the start of an operation of the predetermined peripheral device, and a mode setting unit for setting the system into a mode among the plurality of suspension modes in which the peripheral device can be resumed from a suspension state to an operation state when it is detected by the event detection unit that the event is detected in the case where it is detected by the connection state detection unit that the predetermined peripheral device is connected.
