  • Virtual sleep method
    Publication number: 20070266267
    Abstract: First, an application program is executed on a computer, and then a virtual sleep request is received. Next, the configuration of a CPU, built in the computer, is saved to a RAM. Finally, both the processing speed and the core voltage of the CPU are reduced, and the application program originally executed on the computer continues to run.
