Thank-you. I'm having an issue where the Galaxy Book will not go completely to sleep. The Samsung Logo stays on brightly, whether the cover is open or closed.
Very dangerous heat build-up when this happens, and battery runs down to empty, if not caught.
Will try your suggestion. These Samsung devices seem to have too many similar ways of doing things, which causes conflicts. (ie, Windows-10 Power Saving / Samsung Power Saving / Intel Power Saving...all active simultaneously.)
