An audio device is active 100.0% of the time:

A USB device is active 100.0% of the time:
USB device  1-3 : USB2.0-CRW (Generic)

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


Suggestion: increase the VM dirty writeback time from 5.00 to 15 seconds with:
  echo 1500 > /proc/sys/vm/dirty_writeback_centisecs 
This wakes the disk up less frequently for background VM activity

Suggestion: Enable SATA ALPM link power management via: 
  echo min_power > /sys/class/scsi_host/host0/link_power_management_policy
or press the S key.

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.
