I want my laptop only to charge when under X% of battery is left, while always plugged-in to charger.

I have a laptop that has to be up in running for long periods and I want to lower the electricity consumption as much as possible. Since it is always plugged-in it is always charging.

Also, is this logical, or consumption will still be the same?

Thanks.

  • What brand of laptop? For instance, Lenovo has an app for theirs that allows this behavior.

  • You're doing the right thing for the wrong reason. You will prolong the battery's service life a little with this practice (although you risk running out of juice when you need it). You won't save electricity because there is negligible charging current when the battery is full.

  • Charging is controlled by the bios, no way to change its behavior.
