thanks for the hints by following tutorial from http://technowizah.com/2007/01/debian-how-to-cpu-frequency-management.html i set my cpufreq to "conservative" but does this setup shuts down wireless card from time to time because my wireless connection sometimes goes on and off? # cpufreq-info cpufrequtils 004: cpufreq-info (C) Dominik Brodowski 2004-2006 Report errors and bugs to cpuf...@lists.linux.org.uk, please. analyzing CPU 0: driver: powernow-k8 CPUs which need to switch frequency at the same time: 0 hardware limits: 500 MHz - 2.00 GHz available frequency steps: 2.00 GHz, 1000 MHz, 500 MHz available cpufreq governors: powersave, conservative, performance current policy: frequency should be within 500 MHz and 2.00 GHz.
