Systems and methods for power state transitioning in an information handling system

A computer program, stored in a tangible, non-transitory computer readable medium for power state transitioning in an information handling system having a volatile memory and a nonvolatile memory, comprising executable instructions to cause at least one processor to:

• identify data in the volatile memory which has been modified or not previously stored in the nonvolatile memory, wherein identifying dirty data comprises checking a flag within the volatile memory during process idle periods;
• transfer modified or not previously stored data from the volatile memory to the nonvolatile memory at least partially on an opportunistic basis, based, at least in part, on a usage level of a component within the information handling system;
• transition to a reduced power state in response to a trigger event;
• transition from the reduced power state in response to a wake signal;
• copy data from the nonvolatile memory to the volatile memory;
• update a record to reflect that a current instance of the dirty data has been stored;
• record an alternate copy of the flag for standard operating system usage of the flag;
• reset the flag;
• and
• wake an operating system to a restored state.

An information handling system, comprising:

• a processor communicatively coupled to a volatile memory and a nonvolatile memory;
• a computer readable medium comprising instructions that cause the at least one processor to:
• identify data in the volatile memory which has been modified or not previously stored in the nonvolatile memory, wherein identifying dirty data comprises checking a flag within the volatile memory during process idle periods;
• transfer modified or not previously stored data from the volatile memory to the nonvolatile memory at least partially on an opportunistic basis, based, at least in part, on a usage level of a component within the information handling system;
• transition to a reduced power state in response to a trigger event;
