When I had windows I used lenovo energy managment and set the battery to charge up to 60% only as it recommended it to me. Yesterday I switched to Ubuntu and now I have this problem. It would be great if I could fix this without installing windows again. I don't know what all details you will need. Anyway I am providing this one: ashiq-ak@ashiq-ak:~$ acpi -i Battery 0: Unknown, 59% Battery 0: design capacity 176 mAh, last full capacity 168 mAh = 95% Wrong mAh values :/ Please let me know what all infos you need? Regards
