[opensuse] Sony Vaio speed issue - battery normal, AC slow !!!
Hi all I have a Sony Vaio VGN-FS415B laptop running opensuse 10.2. The problem I have is that when the system is running on AC adapter, the system takes about two minutes to boot up and video playback is very jerky despite kpowersave reporting the cpu speed at 1.73 GHz!. This problem is not apparent when running on just the battery, the system boots up in less than a minute and kpowersave reports the cpu speed at 800 MHz. Has any one encountered the same problem and if so how do you go about solving this one?

I only have a few ideas you could try. Check the power management schemes in Yast, System, etc/sysConfig editor, System, Power management. There is one scheme for battery and one for on ac. Maybe try comparing the differences between them and try to change some of the things that are different til you find the culprit. Then, look deeper into that area to get a handle on how to make it do what you expect, or perhaps file a bug report. -- Joe Morris Registered Linux user 231871 running openSUSE 10.2 x86_64 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I have almost the same problem on my Dell. When I switch from mains to battery, there's a CPU spike which lasts for several minutes. I believe it's due to hald, its being confused, perhaps in some loop which takes a lot of processing to resolve. The video is "jerky" probably because it's not getting enough CPU. Try running "top" in a terminal before changing the power source and see what's running. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

That is perfectly normal. On mains the pc runs at full speed. On battery it drops to about half. Usually by changes to clock speed, sometimes by entering a brief sleep mode. You subtracted approx 50% of the CPU capability by switching to battery So the cpu utilization goes up - it still has the same amount of work to do, but its clock speed was reduced by the switch over so it takes it longer to do each thing. This looks like a busier system, because it is busy a larger percent of the available cycles. Nothing surprising here. -- _____________________________________ John Andersen -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
