These default settings are good for use with powerd. They're only applied by /etc/rc.d/power_profile as invoked by devd when power state changes to AC or to Battery, and perhaps? also after boot. See power_profile and /etc/devd.conf for default configuration. *_cpu_freq=NONE has power_profile leave cpu frequency alone, so it won't be altered just until powerd next shifts frequency according to load. powerd also detects power state changes to select its configured mode, which may conflict with a different power_profile setting, momentarily. powerd doesn't care about the *_cx_lowest settings, just power_profile. cheers, Ian
