    My screen dims when I plug in the power supply to charge. When I unplug it and run it on battery, the screen is bright and vibrant again! Shouldn't it be the other way around? Haha. Has anyone had this happen and know a solution? I'm sure it's some silly thing, but I can't seem to figure it out.

    It can be one of two things.
    Either the settings in the power mode selected. Just edit it through there.
    Or a bad video driver used. I had that issue when i played with the installation zip file before installing ;)

    Heya, you can probably find all those related Power managment settings either in Command Center under AlienFusion or when right clicking on the windows battery icon in the system tray, and adjust settings there. You might have some strange settings in power managment, also when using it plugged, i use High performance Profile with default settings, and when it runs on battery it should automaticly change the profile to battery.
    maybe you also adjusted the brightness manually while you were on A/C power, try adjusting it to max again via Keyboard and FN-button while you are on A/C. Same when on battery try to manually lower it via Keyboard. hope that helps as an idea.

    The laptop is always ran on High Performance, even with it unplugged. I just double checked the power plan, and it is showing on high Perf both plugged and unplugged and the auto-dim is turned off completely. I have not changed ATi drivers, recently. I believe I'm still running 10.6, so I'm not sure if something is going on on that side of things. I'm completely puzzled.

    Did you adjust brightness manually then via Keyboard-Button with Brightness Symbol +/- along with FN-button to raise/lower? Also test if when you have adjusted it manually if it is saved when you restart the computer...

    Nope! I did nothing. I just pulled the battery and conducted a power drain. That appeared to have fixed the issue! Oh, how weird these silly little laptops are.


    Edit: Thanks, all, for your helpful suggestions. I appreciate them!
