Summary:A method for transitioning from a first operational mode, where operations are executed on a first processor while a second processor is powered off, to a second operational mode, where operations are executed on the second processor while the first processor is powered off. A driver causes detects a first system event that indicates a transition from the first to the second operational mode is likely. The driver powers on the second processor in response to the first system event and detects a second system event. The driver determines whether each of the client applications can be transferred from the first processor to the second processor without resulting in any data loss, and depending on whether each of the client applications can be transferred, either transfers the client applications from the first to the second processor or continues to cause the operations to be executed in the first operational mode.
