I have an Inspiron 17R SE 7720 but this is a general question about laptops that have Intel HD4000.
Right now I have windows 8.1 and it seems to be running on the HD4000. I didn't install any specific drivers for the nvidia gpu. But maybe windows did? But anyhow I don't have the branded nvidia tray icons.
Since I don't play games, I was thinking it is not necessary to download the 300 mb drivers and install them for nvidia.
I know there is something installed by default from the windows installation in the device manager. But the point of this question is this... is it ok to do what I have done? Just install windows 8.1 and not install any specific video drivers from Dell or Nvidia?
I know that if I install all the drivers properly, they will auto-switch to nvidia when necessary. But my understanding is intel HD400 is quite powerful for regular windows operations and even watching videos, and that nvidia discrete gpus are really just meant for games or other high performance graphics applications.
oops, I keep meandering here... the question is... will, without nvidia drivers from their site or from dell, my computer behave itself (i.e. nvidia lay dormant)? or will nvidia still eat battery unless there is specifically a driver that can autoswitch between gpus installed?
