stamina switch in windows 7

Hi,

I installed windows 7 on my Z21WN, but cannot get the stamina switch to work. Has anyone got a fix? Is there any drivers to download?

Cheers

What version of the nVidia graphics driver do you have installed?

I think you need to install the Sony provided nVidia driver 186.84 - this has extra software to allow switching. The Windows 7 drivers do not have this.

Driver is 6th from the bottom here:

You may have to use the nVidia Uninstaller first (right at the bottom of the page) then put the switch into Speed Mode and install the Driver.
