So i have a MBP retina 15" that has a Windows 7 Bootcamp partition.
The other day I noticed my screen was a little dirty so I took the screen brightness all the way down (fn+ f1) and did this while Windows 7 was locked.
I now cannot get the brightness back up.
I have hard booted and it seems to get back to the Windows 7 login screen. I'm not 100% sure if it's there but if I press esc, I can hear the Windows ting error sound. So it seems that i am there.
Is there any way to "reset" the brightness for bootcamp?
