Hello,
I have been having issues with the battery life on my laptop ever since upgrading to Kubuntu Jaunty. I'm getting around an hour and a half at best, and I find myself charging my laptop every night when I never had to.
I have a Gateway M7315u laptop, which is less than a year old. It came with Vista Premium, and for the entire time I've had the laptop I've been dual booting Vista and Kubuntu, because I am in college and the classes I am taking require Windows unfortunately.
The machine used to dual boot Vista and Intrepid anyway, as I've since removed Vista and allowed Kubuntu to take over the entire drive. I've not regretted it, other than the battery issue. Vista and Intrepid never had an issue with battery life, but Kubuntu Jaunty eats the battery faster than I've ever seen. It usually uses (I'm guessing) somewhere around three minutes of battery life for every one minute spent on battery. With Vista and Intrepid I got around 3 hours, with Januty I'm getting an hour and a half, if I'm lucky.
I posted over on the Ubuntu forums, and their suggestions helped a little bit. I installed and ran powertop, and I followed every suggestion it mentioned. (Even going as far as not using my wireless mouse anymore, which I've always used and never had it cause a battery life issue). I've checked the system monitor and nothing seems to be hogging CPU or memory. I've disabled unnecessary services. I've disabled compositing. I even run on "Xtreme Powersave" when I'm not plugged in. Each power setting usually only gives me 1-4 more minutes of battery life.
The weird thing is, this happened when I changed the entire drive to Kubuntu. I really don't want to install Vista again because I hate it and Kubuntu has all the programs I need and enjoy using, so there has to be a way around this. Any ideas?
