Windows 7 Aero theme when on battery
Solution 1:
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.
Solution 2:
Check the power management settings. It should be in the advanced settings.
Not at a laptop at the moment, but Power Options > Change Advanced Settings
You may need to click on the link to 'view options not visible' (or something to that effect)
Solution 3:
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.
Solution 4:
On my Dell Inspiron 15R, it was the Dell software that was the culprit.
Right Click on the battery icon » Dell Battery Meter » Uncheck "Enable Dell Extended Battery Life".
Then Click Settings below this and uncheck the 'Switch to Windows 7 basic' option.
