I have a Lenovo Legion Y720 laptop with an Intel CPU plus an NVIDIA GTX 1060 6G. I know it is possible to have the NVIDIA turned off (unpowered) when not gaming, to save battery life, and to have it turned on automatically when gaming and other uses when graphical performance is needed.
Currently my NVIDIA is always turned on. If I click the little arrow in the tray of the task bar and hover over NVIDIA Activity icon, it is partially green and says
1 display, 0 programs.
I have a friend who has a laptop with a similar Intel + NVIDIA configuration, and that icon is grey on his PC; hovering over it shows
Inactive. When he starts Minecraft, it turns green and active.
I've tried searching the web, but can't find a solution; most of what I find are people trying to force the NVIDIA graphics to run all the time, which is opposite of what I want.
So how do I ensure that Intel's graphics display adapter is used when it is adequate, and that NVIDIA is powered off and not consuming energy except when needed?
