So I'm not allowed to adjust brightness any other way now? I also feel that the Intel Graphics Control Panel brightness adjustment doesn't really help in terms of battery life. Feels as if the color of the screen has decreased by the brightness of the screen itself remains the same.
I'll try downloading this Iris driver thing.
Also, I've been lately getting several BSOD's. Sevenforums suggest it might be driver related issues:
BSOD upon closing lid - Page 6 - Windows 7 Help Forums
Any suggestions?
