About a month ago, I installed Ubuntu 14.10 on Lenovo T430 removing the current OS Windows 7. First two - three weeks everything was working smoothly. After then, my laptop started to overheat and battery life started to drain quicker. It fell down from 2.5 hours to approximately 1 hour. Although I have been using it for more than a month I am still new to Ubuntu. Any help is appreciated.

  • overheating could also be the hardware. Battery life depend on how you used it and taking care of it. Not always Ubuntu. Dec 22, 2014 at 5:45
