Windows 7 Aero theme when on battery

"This is how I got it working.

Change the power profile to ""Power Saver"" (How to: Right click on the battery icon on the desktop > select ""Power options"" > Select ""Power Saver"")
Unplug the charger and then go to ""Personalize"" (right click on the desktop select ""Personalize "")
Click windows color > switch OFF ""Enable Transparency""
Save changes and exit ""Personalize""
Plug in the charger and then go to ""Personalize"" (right click on the desktop select ""Personalize"")
Click windows color > switch ON ""Enable Transparency""
Save changes and exit ""Personalize""

I think this should solve your problem."

"You need to change the visual settings in Windows to ""Let Windows choose what's best for my computer"".

Start -> Right Click Computer -> Properties -> Advanced System Settings -> Advanced (tab) -> Performance: Settings -> Check ""Let Windows choose what's best for my computer""

REBOOT PC

Windows will now disable the aero transparent effect when running on the power saver mode unplugged. Cheers."

On my computer (a Dell) there is an section in the Advanced power settings called Dell Additional settings. The options in there let you turn off Aero Glass and the sidebar when on battery.

Install Vista Battery Saver. It works fine on Windows 7 as I use it myself. Not only can you have it disable Aero when on battery, you can have it switch between power profiles. For instance, I have my laptop run on high performance when plugged in and then it switches to the battery saver profile when running off of the battery.

I recently tried this, I posted last time, but it' still wouldn't change automatically. Try opening til Performance Windows while being in the power saver mode, then choose to disable the aero glass, then goto balanced power scheme, then choose "let windows choose what's best..." now it should work, but it seems that you have to choose it when ur in power saver mode.
