>This is not a solution at all. Post says this only works with lid closed, but most MPB16's will achieve reduction from 20W to 8-9W just by closing the lid, with no settings changes needed.

Of course, because you can dissipate enough heat with the lid closed.

>That being said, 8-9W with closed lid is still high. Consumption for second monitor when it's idle shouldn't be more than 1W.

I am not about that, because laptop displays draw more power than 1W most of the time. (I'm aware of those low power displays that Lenovo utilizes.)

And there are a couple of factors that I've forgotten.



These power numbers are for the discrete GPU, not for the displays.
