ABSTRACT:
A network hibernation system and method for a computer connected to a network, comprising a power management controller for generating a time-out signal when the computer fails to provide an event signal indicative of an active operational state of the computer, to the power management controller within a predetermined time period, a data back-up power supply for generating an ac-down signal indicating that AC-power supply is abruptly interrupted, an OR gate for outputting a hibernation interrupt signal in response to the time-out signal and the ac-down signal, a network interface for connecting the computer to the network, the network interface generating an network event signal in response to data being received over the network, a network hibernation information memory for storing current information of the network interface, a system control part for outputting a control signal in response to the hibernation interrupt signal, wherein the control signal prevents the power management controller from processing the network event signal generated by the network interface, a random access memory for storing current operating state information of the computer, the random access memory having network hibernation information memory area for storing current information of the network interface, an auxiliary memory for receiving and storing the current operating state information and the current information of the network interface from the random access memory in response to the control signal, and a non-volatile memory for storing hibernation state information.
