We don't do hibernate.  Hibernate saves active state to file on your 
storage media and powers off then reloads the file on boot.  We only do 
suspend. We call it suspend because its suspend-to-ram in ACPI speak. 
I've been calling it ASR or agressive suspend/resume because most 
systems only suspend when you close the lid or after it sits idle for a 
long time.  But we have our settings measured in seconds rather than

ASR not hibernate.

On purpose.  Default powerd config will wake up and turn off the machine 
if its been in-suspend for 4 hours.
