A USB device is active 100,0% of the time:
USB device 8-1.4 : G15 Keyboard (G15 Keyboard)

Suggestion: Enable Device Power Management by pressing the P key


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


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 the CONFIG_INOTIFY kernel configuration option.
This option allows programs to wait for changes in files and directories
instead of having to poll for these changes
