holr Posted November 1, 2006 Report Share Posted November 1, 2006 Hi, I am running mandriva one 2007 kde on a thinkpad t43p laptop. When i am running from the battery i have klaptop set to run the computer in a low-speed 800mhz mode, which it does (as confirmed by cpuinfo from kde-apps.org). However, when I have the laptop plugged into the power, again, trying powersave mode, it jumps up to 1.6ghz. (the processor is a 2.13 centrino / pentium M by the way). Is there someway of getting the laptop to run slower when in powered mode - as it tends to get quite warm when its unnecessarily running fast!

holr Posted November 1, 2006 Author Report Share Posted November 1, 2006 whats weird, is when i unplug the laptop from the mains, it goes down th 800mhz, when i plug the power in, it goes to a minimum of 1.6gig, with periodic chanages up to 2.1gig (it automatically changes the cpu governor from ondemand to performance from time to time!)

JonEberger Posted November 2, 2006 Report Share Posted November 2, 2006 i have a similar problem with klaptop on a similar (but slower) machine. by problem i mean that klaptop changes the profile from what i've set manually. but i really don't care about power when i'm plugged up. it's no different than a desktop then.

uralmasha Posted November 2, 2006 Report Share Posted November 2, 2006 Not sure which daemon is used to switch the frequencies, since I am using a desktop, but if that's cpufreqd, it may have a default setup with rule that truggers frequency boosting when plugged. Have a look at /etc/cpufreqd.conf , the file is pretty well commented. Quote Link to comment Share on other sites More sharing options...
Mhn Posted November 2, 2006 Report Share Posted November 2, 2006 It could also be laptopmode that does something... Quote Link to comment Share on other sites More sharing options...
holr Posted November 2, 2006 Author Report Share Posted November 2, 2006 (edited) i tried playing around with /etc/cpufreqd.conf, and saw the default for the "ac profile" w as max performance. I changed it to ondemand, rebooted, and it is working fine now (800mhz most of the time, spikes to 2.1 wh en it needs to be!). Im not sure if i can change the values with klaptop properly yet, but it works the way i want it now, so time to leave well alone! Thanks for your help! *update* Seems like it was still doing funny things, I couldnt figure out why. I actually deleted (rather renamed) the original /etc/cpufreq.conf and this seemed to sort it out properly. I havent had any issues for over a week and klaptop is switching cpu frequencys nicely now.
