Under System Preferences -> Displays, I have unchecked the "Automatically adjust brightness" box so that the OS will not automatically adjust the brightness.  However, every once in a while (probably every couple days or so), it will randomly adjust the brightness to some arbitrary level. 


I can understand it doing so if I have that box checked, but I don't have the box checked, so shouldn't it remain at the brightness level specified with the slider above that checkbox?


Yes, I have restarted the computer, shut it down, reset the SMC, etc...
