i would like to hear your opinions about power consumption of a machine powered by ubuntu versus windows. this thing would only be possible if you have dual boot.
let me give you my results:
on windows ~22W
on ubuntu ~24W (only if i put the graphic card on "low" profile. if i use "default" i have 26W)
try to test using the same condition that the result to have any value.
on windows a use batteryCare and in ubuntu use powertop.

so, based on the measurements, what can we do to have the same power usage as windows?
