Abstract
A method and system are disclosed for efficiently storing an operating state of a data processing system having a volatile memory within a nonvolatile mass storage device. In response to a selected input, a determination is made whether storing the operating state of the data processing system is possible. If storing the operating state is possible, scheduling of tasks to be performed by the data processing system is halted. Data not required for operation of the data processing system is then removed from the volatile memory. The operating state of the data processing system is stored within the nonvolatile mass storage device, thereby enabling the operating state of the data processing system to be efficiently restored. Thereafter, power is removed from the data processing system. In response to restoring power to the data processing system, a determination is made whether the operating state of the data processing system is stored within the nonvolatile mass storage device. In response to a determination that the operating state of the data processing system is stored within the nonvolatile mass storage device, the operating state of the data processing system is loaded from the nonvolatile mass storage device, thereby restoring the operating state of the data processing system.
