Abstract:
A power management method used in a computer system, in which data stored in a main memory is stored on a hard disk when the computer system enters a suspended state, wherein:when the computer system resumes from the suspended state, it is determined whether a power controller for controlling the power of the computer system has been initialized after the computer system entered the suspended state, and: if it is determined that the power controller has not been initialized, then it is determined that no interruption of the AC power of the computer system occurred, and the computer system is made to resume the previous state before the suspension, based on the data stored in the main memory; and if it is determined that the power controller has been initialized, then it is determined that an interruption of the AC power of the computer system occurred after the computer system entered the suspended state, and the data stored on the hard disk is read out and the computer system is made to resume the previous state before the suspension based on the readout data.
