When running Windows 7 RC via battery, the graphics wash out to a point where using the laptop is near impossible. I have checked my power management settings and there seems to be no issue there. Any ideas?

You've said you checked your power management settings but haven't said what they are. It would be easier to provide feedback if you provided some details on that front.Which power management mode are you using; what is the screen brightness setting for battery vs AC; does it swtich to non-Aero if running in power saver mode; what's the graphics adapter, etc.?Stephen
