Hello,

I had a Latitude E6400 laptop and I recently substitute with a new Latitude 5480. There is an option on E6400 that stop charging the battery by pressing Fn+F2 when the laptop is plugged in AC. This ability helps me to maintain my battery completely healthy over 9 years!

However, I cannot find this option on Latitude 5480. Is "primarily AC use" in "Dell Command | Power Manager" works the same automatically? 

Also it is not clear for me what is the "Adaptive" option in "Dell Command | Power Manager" and how it works?
