** Description changed: - In idle mode my notebook consumes ~10W, but when I launch powertop 2.1 - power consumption doubles. + In idle mode my notebook Samsung 300E5Z consumes ~10W, but when I launch + powertop 2.1 power consumption doubles. I check power consumption by monitoring /sys/class/power_supply/BAT1/current_now (it's value raises from 900000 to 1700000 when powertop runs) CPU temperature reported by lm-sensors raises by 8 °C after powertop launch. It does not look like powertop uses CPU much though: top shows <10% CPU usage and according to cpufreq-info CPU stays at 800MHz As soon as I exit from powertop power usage returns to idle. Purging and reinstall powertop package does not help. I also tried removing /var/cache/powertop/saved_*.powertop but it did not help, either (BTW, I suppose saved_parameters.powertop should be cleaned by package purge...)
