I just got a replacement MacBook Pro from Apple. I got a new one that had issues, and they sent a replacement. Everything seems to be working great on the new one, except I now have some odd behavior with the LCD backlight. If I leave the computer running, and turn the backlight all the way down to off, it will turn itself back on to the lowest brightness after a couple minutes. So it will turn off for a couple minutes, turn itself back on, then it will timeout and turn itself back off again. Any idea why this could be happening? Very strange.
