At work, I have a MacBook Pro 2.2 GHz Intel Core i7 attached to an Apple 24-inch LED Cinema Display.
I have it set with the extended display option with the Cinema Display is set as my main display. On both displays I have the brightness set all the way up and "Automatically adjust brightness" unchecked.
Whether I'm waking the computer from sleep or starting it up cold, the brightness setting on the MacBook Pro is always reset to the middle position. The brightness setting on the Cinema Display is at full brightness as it should be. On both displays, "Automatically adjust brightness" remain unchecked.
Why is the brightness setting on the MB Pro not sticking and how can I make it stick?
