    Hi guys!

    I've had Leopard installed for a couple of days now and I'm really pleased with it. Seeing that Boot Camp was included with the OS I decided to try it out, mainly because VLC ain't effective enough for 1080p all the time and some applications I use for education are Windows specific.

    Anyhow, the installation worked fine and after installting the Boot Camp drivers everything ran smooth. That was... until I disconnected the power cable. Then all of a sudden the screen starts behaving weird. It's not that the backlight brightness are adjusted, it's more like the color profile being changed on the fly. It happens when I open up certain windows and is very obvious when leaving the background/wallpaper visible in the back.

    Let's say that I open up network connections and from there open up properties for my WLAN connection. At this time the display's looking fine. But then I open up settings for the Internet Protocol and the screen gets very bright. It's raising contrast to the point of destroying the highlights in the wallpaper image. When I close the window the exact opposite happens. The contrast then gets dropped leaving the image looking washed out. I should mention however that it doesn't do it equally much all of the time. Sometimes it's more apparent than others.

    So to sum it up. Everything else works fine. I have the standard sRGB profile set for the monitor. It works with my 24" Dell external monitor just fine, at least with external power connected. But yea, when I disconnect it and it runs on battery, it somehow seems like the graphics card are doing some "nifty" power saving thing, but to me it just seems like a bug.

    I've searched google and several forums but come up with nothing. Maybe my searchs aren't good enough or this problem hasn't popped up anywhere else yet.

    Hope you guys can help! Thanks in advance!

    Edit: Oh, I should also mention that I'm running Windows XP Service Pack 2, and the computer is a MacBook 2.0GHz C2D w/ 1GB of RAM. The previous black MacBook I guess.

    Ok guys, a little update! I'm happy to say that after installing like 100 updates from Windows update, the problem has disappeared. I thought my system was completely up to date since it didn't download any updates and it is an SP2 install after all. But before quitting out of Windows yesterday it installed several updates and today I tried to "repeat" the problem like I did the other day but it didn't show up. So.... guess Windows was doing what it does best, being buggy ;-)
