Upgraded to Windows 7 32bit. Generally a smooth upgrade, not perfect though.
When I am switched into the performance mode for my graphics, therefore using the ATI card, I cannot switch powerplans. Nothing happens if I select a change. As well I cannot with the hotkeys or through any program change my screen brightness. Once I switch back to the intel graphics card, I can switch power plans again and change brightness without any problem.
Is this a known problem? Is there an easy workaround?
