Alright well I'm experiencing a rather strange bug and at first I thought I was going nuts. For some reason on my my MBP 2008 the screen dims itself. And auto dimming is off! I keep auto dimming off when plugged in, and while working all of a sudden the screen will dim a few ticks. I then have to F2 them back to full. I never had this issue until I installed SL, I did a clean instal BTW. Anyone else having this issue?
