Hi
I have been working on Fedora since Core 6, and found that now I've moved i've had to start using my battery more on my laptop than I used to. So my battery just doesn't last. I got myself a replacement thinking that my battery is dead but still had the same result. I am running an HP NC6320 laptop with nothing extra (clean install). My brightness is on the lowest setting. I went through my services and stopped all the ones I don't need and installed powertop and did what it told me to do, (but it is not permanent for one). According to HP my battery should last about 4 hours, however I only get about 1.5 hours if I am lucky. I have to say when I was testing this on Windows I did not get 4 hours as HP say but got about 3 hours. So running Fedora cut my battery time in half. One thing I did see on powertop is that my "Wakeups-from-idle per second" is running at "669.1 interval: 10.0s", this looks high. How do you reduce this? Is there anything else I can do to get more battery power out of it?
Thanks Chris
