X1 Extreme Event Viewer "Event 137 Kernel-Power" When Going to Sleep

I have consistently recieved this error "Event 137 Kernel-Power" message in Event Viewer when I place my X1E into sleep via the Fn-4 key method:


"The system firmware has changed the processor's memory type range registers (MTRRs) across a sleep state transition (S4). This can result in reduced resume performance."


I don't notice anything in performance or other adversity but thought the Lenovo firmware engineers should be aware of this event. I am running UEFI Firmware 1.17 and Windows 10 Version 1809.
