The setting (I don't know the name) is intended to maximize battery life which is tied to the number of recharge cycles. Often once the setting is selected it charges most of the way but will not begin charging again until the charge %age drops low enough. Most lithium ion batteries send their charge info to the unit they power via a protocol called I2C. The battery tells your laptop how much charge it has. Your pc can't tell on its own.

The % charge indicator is more of a "best guess" than a precise measure. hunter Nov 2016 #11
