I've recently purchased Lenovo S4000 Ideapad laptop & have installed Ubuntu 12.04 on it along with windows 7.
Well whenver I login to ubutnu, it shows me 00:01( that is 1 minute) or 'unknown time to charge' message.
Also, the battery drains very quickly, approximately in an hour.
However the battery works considerably fine with windows OS.
Please let me know, what has to be done?
