I wonder if powertop may be of use here.  

It has a "tunables" section where (I think) power-saving features can be toggled between "good" (on?) or "bad" (off?) by pressing Enter or Space when selected, though neither man powertop nor its (github) website 

01.org/powertop

explains the significance  or difference between "good" and "bad", but maybe worth trying?

Best wishes,
