Backlight on LCD refuses to change.
The title says it all, I guess...
I have no programs installed that will automatically (or otherwise) adjust the backlight settings. When I go to the Power Settings and change the backlight levels, nothing happens. Not so much as a flicker.
When I install something like Lumos, calibrate it (the light sensor is functioning), and tell it to do its thing... the backlight doesn't change.
All of this is even after (several...) soft-resetting.
Can anyone shed some light (haha) on my situation?
