Put a C2 with disabled ASBL right next to it and the difference will be obvious (at least after a while) when using it for productivity.I haven't really noticed this outside of when I actually had static content on my screen and wasn't using it. Then simply moving my mouse on it immediately woke it up. There was only one isolated incident where it sort of refused to push the brightness back up. So perhaps recent firmware has improved by leaps and bounds in that category.
