Abstract:
Systems and methods for power state transitioning in an information handling system having a volatile memory and a nonvolatile memory are disclosed. Dirty data in the volatile memory may be identified. The dirty data may include data that has not been stored in the nonvolatile memory. Dirty data may be written from the volatile memory to the nonvolatile memory. Transitioning to a reduced power state may be in response to a trigger event. Transitioning from the reduced power state may be in response to a wake signal. Data may be copied from the nonvolatile memory to the volatile memory. An operating system may be waked to a restored state.
