I am new to the linux world. I recently installed ubuntu 16.04.1 in my Lenovo Yoga 500 laptop. Now my laptop's battery backup become very low. it only give me 1.5 hours to 2 hours backup. In windows 10 it gives me almost 4 hours backup. And I am facing heating problem also. I'd tried to install powertop but unable to use this getting some error
powertop: error while loading shared libraries: libpci.so.3: cannot open shared object file: No such file or directory
Battery 82% and time remaining 1:52
How can I fix these problems?
