I own a [Lenovo Z410][1] laptop, and its battery is not removable. Lenovo published an ['energy management' driver for Windows][2] that let you to use ac power instead of battery when the battery power is between 55% and 60%. How may I do this in Ubuntu?
I notic that if i turn on this option in windows and restart to ubuntu whitout unpluging charger, battery doesn't charging and device use ac power.

[2]: you're right. It's a driver. But when you install it, an app named "power manager" appear in app menu.
