The power savings options are grayed in GMA options? Is this normal and does some drivers enable the use of these?

Do you have Power Manager installed also?

Yes, installed it, but the options are still grayed, and the manager doesn't have GPU power management option. Can you access GPU power management?

Have you installed the Power Management driver or the ACPI driver?

I just checked the Intel display driver panel on the Windows 7 X41T, all the power related options are greyed out as well.

Ok, dug a little deeper. GMA900 Power Savings Technology isn't about reducing voltage of the GPU, but reducing picture quality by lowering contrast etc. http://www.istartedsomething.com/200907 ... g-feature/

So there isn't really a usable benefit in using it anyway.
