    ubuntu 13.04 Raring Ringtail short battery life

    hello!
    i have just installet Ubuntu 13.04 on my Samsung RC-530 S02, and I'm liking it very much. but i have one problem I would like to solve: i m noticing that this new OS is consuming too much energy. before installing it, i used ubuntu 12.04, and my battery life coult reach 6 hours (if i kept mininum brightness). now it hardy reaches 1 hour and 45 minutes. furthermore, i can hear that the PC's fan is working much more than before. can I do someting to change this?

    thanks

    wrong idea.....
    if the fan is constantly working at a high speed it means that you have a big load on your processor. open "top" and detect that process.
    this is usually happen because of video driver.
    to be honest....i would wait 3 months before will eventually install 13.04, i am sure that it will become more mature!

    I've just tried to do what you have said. doing this, i have also noticed that the system monitor is not working well: it said that all processes were using 0% CPU, while using "top" from the terminal i found out that thunderbird was using 50%. but, except this, no other process is charging my CPU, ad now it is at 3% usage. ad so it was before i started thunderbird obviusly. but the fan has not really slowed down.
    I also know I should have waited some more to install 13.04, but i 12.04 was overloaded with programs and was slowing down, so I 've decided to reintall now. if i can't manage to solve this, I'll try debian i think. I don't want ti have such a noisy PC

    If you wait too much, better wait more and install Saucy. Only issue here is the wireless card driver.

    But try installing TLP, it really makes a difference here.

    I would normally suggest that too, but now the support cycle is 9 months instead of 18, so that has to be factored in, maybe waiting for a month or a month and a half makes more sense.

    I've installed it, but i really don't have unterstood how to make it work. It is already running i think, since i have restarted my PC, but nothing has changed

    Maybe you should post your issue in the General Help section, the guys there will be able to help you more than I do.
