Hi
Just got this the other day. What does the VGA button do on the top left? Its normally on amber and when you press it, it goes green. Assume it swapping the GPU but which is on and which is off ?

I think green is the Nvidia chip and amber is the Intel intergrated graphics chip.

Green: Nvidia GPU will not be used whatever the settings are.
Amber: Nvidia GPU will be used in 3D or similar applications.
