Optimus is nVidias technology for notebooks to disable the dedicated GPU when not needed and use the CPUs integrated GPU. Hence the naming of this topic.
Wanted that too: Use the iGPU for the 8 hours of office task, kick in the extra GPU for relaxing after hours.
Would save electricity, so my thinking. Never got it to work on any of my previous machines. Roundabout this post, the idea re-emerged.
Well, easy, set BIOS-setting
Advanced -> System Agent (SA) Configuration -> Graphics Configuration -> Primary Display
to
Auto
and ready to go.
Office closes, unplug the lower million watt power supply, change the HDMI connector for the monitor et voila.
A little fiddly, works though. The PC has to be shut down when changing from office to power mode. Now way I figured around that; even tried hot-plugging the power supply. Does not kill the PC (obviously, duh), but does not help you in any way, and it is dangerous, hence stupid.
With the additional M.2 SSD installed (there are better posts on this by now, even videos), and the extra CPU cooler whirl up at start
Advanced -> CPU Configuration -> Boot performance mode
set to
Turbo Performance
the booting is seconds. Who cares.
What got me especially annoyed, was the HDMI-fiddling. Plugging the million watts power plug *pf, the HDMI though *grrr
The first idea I came up with was this:
Two short hdmi-cables, a longer one and an hdmi connector. Got me happy for some time. Though, after I saw at a friend of mine (just joking here, I don't have friends in IRL) switching between his million gaming stations it arouse this idea:
<camera issues here>
An automated switching device, powered by the short .5 meters hdmi. As we got to shut down the G20 anyway, who cares.
With the oompf-button at my feet, this is what I ended up with.

Perhaps this is an idea for you, perhaps you got some spare parts lying around. I thought this is an idea worth sharing. Save the planet.
