Hello, I hope someone can provide some help for this issue I'm having. I'm using bootcamp 1.3 drivers + Vista 32bit. On startup the brightness is at maximum. I can go one tick lower by hitting Fn+F1 (the smaller sun) and all is well. If I try going down one more tick my computer freezes each and every time so I only have 2 brightness settings. Luckily, the second to last tick is noticeably less bright than maximum so for the mean time it's not unbearable. I've formatted and reinstalled vista about 3 times now and didn't have this problem with bootcamp 1.2. It always occurs with 1.3, though.
