I have Ubuntu 14.04 dual boot with Windows 8.1. Windows is working perfectly fine but in Ubuntu, Laptop battery discharges slowly than the rate at which it used to discharge previously, and my PC shuts down immediately as the battery is reached around 65-70%. There is no problem with charging as after Shutting down, it charges uniformly from 0% to 100%. How to fix this?
