Hey, I don't know if anyone else has experienced this, but I thought I'd just chip in and let you know. When using this workflow to restart into windows 7, it stops me from being able to turn my brightness up and down. However if I manually boot into windows it's fine, same goes for choosing windows as my startup disk. At first I thought it was to do with windows update updating my drivers, but it's not.
I was wondering if there was a fix for this workflow so that my brightness would work? If not I just wanted to highlight the problem for other people that might of experienced the same thing and not known why it was happening.
This is what I discovered regarding the problem. Original Discussion
I also see this problem on a MacBookPro 8,2 (late2011):
*When booting Windows 7 with rEFIt, brightness control does NOT work. *When booting Windows from the option menu at startup, brightness WORKS. *When booting Windows using Startup Disk pref. pane in OS X, brightness WORKS. *When booting Windows from the Windows Boot Camp program, brightness WORKS.
When the brightness works, both the keyboard shortcuts and Windows Control Panel controls work. When it doesn't work, neither the shortcut keys nor the Control Pane controls work. Based on this, I infer that it's something to do with rEFIt.
I wonder if anyone who uses rEFIt has the skills to debug and code up a fix for this type of thing. I don't
