An information handling system includes a processing system, a low-power processing system, and a chipset. The processing system is configured to operate using a power system configured to power a shared resource of the processing system and a non-shared resource of the processing system, and to disable the non-shared resource during a reduced operating state of the processing system. The low-power processing system is configured to access the shared resource of the processing system during operation of the low-power processing system, wherein the operation of the low-power processing system is separate from the operation of the processing system. The chipset includes a processor of the processing system and operable to be enabled during operation of the processing system, wherein the processor is configured to be disabled during operation of the low-power processing system.
