title: Hibernate a BeagleBone Black
body: <p>I'm a student, I am a beginner with beaglebones. I have a project and in the project we have a BeagleBone Black connected to a battery and solar panels.
  It will work autonomously, and the beagle will send datas by the 3G network through an 3G usb. 
  What I want to do is to save as more energy as it's possible. What I thought first was to switch on hibernation or sleep mode the beaglebone. To switch on hibernate/sleep mode and then wake up the Beagle every x seconds or minutes or anything else. 
  So I want to know if it's possible and if there is an OS more adapted for that use. 
  I succeeded to disable the usb chipset and then to reactivate it several minutes later.</p>
  
  <p>Thank you if you can help me !</p>
