An audio device is active 100.0% of the time:
hwC0D0 Realtek ALC269 

A USB device is active 100.0% of the time:
USB device  1-8 : CKF8156 (Chicony Electronics Co., Ltd.)

Suggestion: Enable USB autosuspend for non-input devices by pressing the U key


Suggestion: Enable the ondemand cpu speed governor for all processors via: 
 echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor 


Suggestion: Enable wireless power saving mode by executing the following command:
  iwconfig wlan0 power timeout 500ms
This will sacrifice network performance slightly to save power.

Suggestion: enable HD audio powersave mode by executing the following command:
   echo 1 > /sys/module/snd_hda_intel/parameters/power_save 
or by passing power_save=1 as module parameter.

The program 'rsyslogd' is writing to file 'auth.log' on /dev/sda5.
This prevents the disk from going to powersave mode.
