That was until a software update a couple of days ago. Before the update the brightness could be set at a range of values, using both the builtin keyboard function keys, and the settings control. After the update the brightness can only be at minimum or maximum values (keyboard function keys and settings control) and the brightness control display stutters when trying to select anything inbetween.
