I'm using an Asus L200HA ultrabook as a secondary for school work.
I know it has a decent luminosity when it's pluged in, but, unfortunetly, it is NOT the same when I'm on battery, and, when I'm on the netflix app, the luminosity goes back and fourth pretty weirdly.
Do you have any tricks on how to control my lominosity better then what windows usually allows ?
Uh this might be a long shot, but try going into Power Options and make sure Enable adaptive brightness are both Off for On battery. Also check in the Intel Graphics settings that Display Power Saving Technology is disabled.
