Dell Latitude 5490 Power Consumption.

I have successfully installed Big Sur on a Latitude 5490, almost everything works fine.

I noticed that when I turn it on for first time, the DRAM value is always higher than 1, if I restart these values when idle drop to values lower than 1.

Someone has any clue of what can be happening?
