Enable laptop to use direct power when plugged in and battery is full

[M_R_James]

Hi,

I normally use my laptop at the office daily.

Most of the times the laptop battery is fully charged and plugged in.

is there a setting I can enable to use only direct power when plugged in and battery fully charged? 

This is to try and protect the battery from overcharging and heating.

Hello.

There is no such setting. The power delivery design in laptops makes it possible for you to disconnect the laptop from AC power at any given moment and the battery will still keep the laptop powered on without a hitch.

Your laptop charging circuitry will not try to charge your battery endlessly, the battery will not overcharge. When the battery is at full charge, the charging will stop. When the charge falls below a certain internal threshold, the charger will top the battery again. If you were to put an electricity usage meter between your wall socket and the laptop AC adapter, while leaving the computer idle, you could monitor and see the moments when the battery is being charged as higher energy usage.
