Hi, >If you managed to get improvements yourself, please let us know on the mailing list.
So here are my results: On my old laptop (celeron m 1,3Ghz) I played around with the different kernel options and to some extend with different versions. I started with a 2.6.16 kernel - powertop showed me that - it receives 1000 wakeups (is that related to the 1000hz option? ) - it uses 15,4 Watts (with lowest background-brightness of the display) - and the cpu is stuck in C0 / C1 - 163 mhz while idle* (100%) (and of course no timer stats available) (*idle = fluxbox + eterm (running powertop)) using powertop hints and upgrading the kernel to a 2.6.24-rc2 got me to following: - 40 wakeups (mostly due to extra_timer_interrupt (29)) - 11,7 watts longterm (with lowest background-brightness) - cpu reaches now c3 (95%) - 163 mhz while idle* (100%) - HPET doesn't work :/ So almost 25% saved power! (Unfortunately it doesn't really improve my battery runtime - as the battery somehow is broken (10 minutes ! when charged full)) ---> To put it in a nutshell - upgrading the kernel and configuring it with help of powertop + wise choosing of application saves a lot of power. ---> Do you think there is still room for improvement? ---> I have an intel ICH4 Chipset -> Hpet possible? Anyways - I thanks for that great app. Regards, Peter _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
