Im a newbie to linux and I've installed Fedora 18 on my Dell Inspiron 15R N5010 laptop. I feel the battery drains a lot faster than in Windows 7. I've installed powertop to tune the performance but the tuned settings doesn't reflect when restarted. Suggest ways to tune the battery performance.

Note: Battery lasted for nearly 3 hrs in Windows 7 but in Fedora it lasts approx 1.4 5hrs only.

you can try using laptop-mode-tools

Thanx Rabin. Will check for the laptop-mode.conf file and work on this :)

Hi, I installed an app #tuned which helps me choose the mode of operation namely balanced, powersave, etc but i dont find any boost in the battery backup. Can someone suggest me on the ways to fine tune the tuned.conf file?

@radiantracy, currently i'm using TLP for power management * see :

the laptop-mode-tools didn't work for me so good

Found a few suggestions over the internet. Majority suggested #laptop-mode-tools and #tuned as the best option for a better battery backup. I've tried laptop-mode-tools earlier and experienced satisfying performance boost. I get a battery backup of ~3hrs now. Post me if you find a better solution on the issue. Thanks

So you have to create a script to make the recommendations from powertop enabled at startup.

This is a good tutorial.

you can put your script in /etc/rc.d/rc.local and make sure to change the script ownership to root:root and chmod to 755
