[opensuse] Laptop power conservation
Hi all, I have been running SuSE 10.2 on a dual core laptop for a while (looking forward to upgrading to 10.3, but that has to be planned for first). I have had abysmal battery performance from the start (new machine, new battery). I pretty much dismissed this on the "well, Toshiba won't tell anyone except micky$loth how to drive their power management stuff, so I'm stuck with it. However, I just shut down beagle (finally! been meaning to for ages) and discovered that my battery life more than doubled from about 40 minutes to 95 minutes. So, now I'm wondering if there are other things I can do to improve this further. Any suggestions would be gratefully received. In particular, I notice that I seem to have one CPU mostly running full speed (1.6Ghz) while the other core is scaling. Can I "encourage" the system to run both cores at lower speed? (Can I perhaps shut one down altogether, and if so is that sensible?) Anything else that I've not thought of? Cheers, Simon "You can tell whether a man is clever by his answers.

A popular tool that I have used in the past, is powertop. It is a tool released by Intel that looks at running processes and offers suggestions for where to cut back on unnecessary services in order to boost battery life. -- ---Bryen--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I should probably also add that the site for this tool is at http://www.lesswatts.org/projects/powertop/ -- ---Bryen--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

1. Please set your line-length to something reasonable, like 60-70 characters... 2. use the "top" command. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
