ABSTRACT:
A resource allocation request and a resource release request of a PC card modem sent to a communication driver via a modem driver are hooked by a power saving driver. When the power saving driver detects that the resource allocation request is issued, the power saving driver first begins to supply power to the PC card modem by using a card service. Thereafter, the power saving driver transmits the hooked resource allocation request to the communication driver. Further, when the power saving driver detects that the resource release request is issued, the power saving driver transmits the hooked resource allocation request to the communication driver and stops the supply of power to the PC card modem by using the card service.
