I talked lenovo rep on this and he told me that sir the only thing you need to do is a gauge reset. And than your battery will last long since the backup time of my battery is just 2 hrs on normal usage and no gaming.
Hmmm... You can do it at your own risk... Better search for issues, if any, with the battery gauge reset tool first ... If none exist, you are good to go...
