Sometimes one post (P1) is commented "possible duplicate of P2". P2 itself is commented "possible duplicate of P3". Example: [https://askubuntu.com/questions/246610/how-to-increase-battery-duration-hybrid-graphics-notebook][1] is pointed to [https://askubuntu.com/questions/9817/battery-drain-on-ubuntu-is-fast][2], which is a possible duplicate of [https://askubuntu.com/questions/400/tips-to-extend-battery-life-for-laptops-and-notebooks][3]. What can/should we do to improve the situation?
