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 memor…
