I have done fresh install of Kubuntu 12.10 on my HP Pavilion G6 Laptop. I'm a bit nervous that my battery is not lasting more than 1 hour while for Windows 8 it was lasting for 5 Hours(while using MySQL and Wifi)

I have set the brightness to very low has shutdown my bluetooth. But still my battery is not lasting.

Please guide me, how to increase the battery life.

Below are my laptop configuration:

  • Intel Core i5-2nd Generation
  • 500 GB Hard-disk
  • 4 GB Ram 1 GB - AMD Raedon 7600 HD Graphic Card

As advised on another Stack Exchange forum, the procedure to acomplish an answer to your question would be:

adding the following kernel parameters



Adding to /etc/default/grub, Line starting with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm i915.i915_enable_rc6=1 i915.lvds_downclock=1"

(remember to sudo update-grub after editing)
