I have come to notice something odd about the way the brightness on my MBA works. Sometimes I notice that my brightness is not at 100% and I want to increase to see something better or simply because I want the maximum brightness. I will go ahead and press the brightness button and it will display that it is as maximum, yet I know that is not the case. Going back one notch seems to readjust or recalibrate it and the brightness goes up. It is as if the brightness is stuck and once you go back a few notches the computer figures it out. Has this or does this happen to anyone else?
