Patent ID: 6904535

Claim:
An information-processing device configured with at least one communication interface section enabling a wake-up instruction for starting up operationally stopped functional units in a power-off state or a suspend state, a man-machine interface, a memory, and a processor, connected by a chipset having a bus control function, the information-processing device characterized in that: an operational mode for the functional units, when started up from either said power-off state or said suspend state, a normal operational mode use-enabling the functional units in their entirety including the man-machine interface, or an exclusive operational mode use-enabling some of the functional units, including use-enabling said communication interface section executing the wake-up instruction and having performed input/output processing of data, said memory, said processor and said chipset; one of said normal operation mode and said exclusive operational mode is selected according to said communication interface section executing the wake-up instruction, wherein the exclusive operational mode is selected to supply operational power to, and perform information processing on, only resources used in the exclusive operational mode, when the information-processing device is started up according to the wake-up instruction from said communication interface section; and when said exclusive operational mode is terminated, the information-processing device goes to its pre-start-up state, either said power-off state or said suspend state.
