You might also look at tuned...
(I think it was mentioned early in the thread).
tuned-adm profile powersave
Also:
https://docs.fedoraproject.org/en-US/Fedora/20/html-single/Power_Manageme...
Of course it would be nice if this stuff just did the right thing and

Oh my I've barely started readind the above and its great... I wish I
