Need help extending battery life
I've started running Fedora 13 as a dual boot option on my custom built laptop and notice that my battery life runs out in less than an hour... EDIT: After a bit of research from the OEM I found that it is a Compal laptop.
The computer is dual booted with Windows which gets well over three hours so I know its a configuration issue with the laptop. The only real information I can provide is from PowerTOP Code:
Cn Avg residency P-states (frequencies) I can provide any further information if required. |
I believe you can turn off hyper threading in your bios. That's not an ideal solution but it should help with battery life. There are quite a few other reports of this same problem.

Yeah, my research has shown that its a bug in the Kernal but I was unable to find if there were any feasible workarounds. If I disable hyperthreading then my Windows boot will suffer so I'd like to avoid that.
Thanks though! |
? have you turned off unused services ???
http://www.mjmwired.net/resources/mjm-services-f13.html are you using compiz-fusion ? if so uninstall it from a laptop have you used the "power management" tool is this a Gnome or KDE fedora 13 ? have you scaled back on the cpu frequency ? |

2) I've removed compiz-fusion 3) By "power management tool" I assume you mean the tools for setting screen dimming, when to shut off hard disks/screen etc.? If so yes. 4) I'm using a Gnome fedora 13. 5) The CPU is set to On Demand at all times. It sits at 800MHz >90% of the time. I'll report back with the power usage after I get a bit of sample data. Thanks for the help! |
