I have an acer aspire 5742g. My battery life is not good at all. I bought a new battery(not original) and my battery life is about 1h and 40 minutes. With the last battery I had(the original one) my battery life was about 30 minutes. TLP is installed and I have the closed source nvidia drivers installed. Any ideas what can be wrong??? I have Ubuntu 13.10 64bit with Unity. Those times where while using firefox or chromium, skype(logged in but not using it), dropbox and ubuntu one. P.S. I know that there is a serious chance the problem to be with my battery but I still want to know if there is any other problem and if it is possible to find out what is it.
You have a usual problem with Nvidia Optimus technology. Search Internet for solutions that would fit you, for there are many. If you are not gaming, just disable nvidia card.
