Not sure how but just messing around and I found an option called battery saver.
It seems to have been turned off by default.
Does anyone know where it is located and set, if there are any more info about it?
It may make a big difference if I set it on all the time?
I guess it slows the processor down and all kind of things?
My best laptop only give about 2.5 hours max but turning this on could make a big difference?
