I have an Ideapad Touch u430 that came with AOE licence. As it was recommanded, I used the Energy Manager to enable the Economy mode (I don't remember the exact name) that makes your battery stop charging at 59% for a long battery life. It's a Lenovo proprietary software. I installed Ubuntu and deleted windows for good. I didn't disable the Economy mode before making the switch. Ubuntu is working fine, but the battery still stops charging at 59%. It must be something in the bios. But I cannot find it. Since the Lenovo Energy Manager is a proprietary software (a blotware that comes with the computer), I cannot study its code or show it to more experienced developers to reverse this very annoying action. I checked every available solution, they all involve going back to win8/Energy Manager. I cannot go back to Windows, I have no licence now. Even if I install it again, there is no chance to get the Lenovo softwares back.
