Ghost processor?

In my i5 venue 11's event viewer, there are entries while the tablet is completely shutdown. For example, today I turned it on at 9 pm and there were bunch of entries starting at 7 pm all the way to when I turned it on. I find this very strange and wonder if that's why I lose 2% battery over night even if I shut it down. Can anyone else confirm this? Or is my venue possessed!
