Obviously you can just not load the driver, but that will not eliminate power consumption. I have the nvidia card for this laptop as well, but it isn't physically installed so I cannot confirm it would work, although I expect that it would. >> I'll try to explain.

Wiki says no - output is never switches: >When a user launches an application, the graphics driver tries to determine whether the application would benefit from the discrete GPU. If so, the GPU is powered up from an idle state and is passed all rendering calls. Even in this case, though, the integrated graphics processor (IGP) is used to output the final image. https://en.m.wikipedia.org/wiki/Nvidia_Optimus So one can think "unfortunately, my Hasswell/Skylake IGP isn't supported yet, so I will use nVidia with binary driver". Then he tries and has no success because still required to load driver for IGP even if not uses it directly. >> Latest supported Intel graphics on FreeBSD is that comes with Ivy Bridge.

For my needs, Haswell/Broadwell doesn't provide much value over Ivy Bridge and Sandy/Ivy Bridge models are still in a sweet spot for used pricing. > > All in all it's a nice laptop which has allowed me to get rid of several other systems. However it is big and heavy. It does not fit in standard laptop carriers eg a laptop backpack, and it has a hypersensitive touchpad. But there aren't many laptops capable of of 32GB RAM along with all its other power.
