startup-0.9.8.38-alt1 According to powertop , on my laptop (Dell Latitude), the things that constantly consumed most power were: Audio codec hwC0D3: Intel Audio codec hwC0D0: IDT and powertop even has a "tunable" to mitigate this problem: "Enable Audio codec power management", which has a huge effect indeed. Can't such a setting be put into the default configuration?
powertop does this: echo 1 > /sys/module/snd_hda_intel/parameters/power_save

(xint) parm: power_save_controller:Reset controller in power save mode. (bool) One may consider other greater number of seconds, too, if one wants to enable power-saving...
