   Laptop or desktop?   
     The former has different 'On Battery' Power Options which would seem to   
   be necessary and configured with 'Hibernate' for any signal from the UPS   
   to communicate a valid request to the device to re-enable Hibernation(if   
   disabled).   
   For desktop devices, it seems to reason that Windows would have to   
   recognize the UPS as a battery(which a desktop by design does not have)   
   for an 'On Battery' Power Option configured with 'Hibernate' for valid   
   communication between the UPS and Windows to effect a hibernate condition.   
      
   AS noted, UPS devices(alone and without other software(add-on or built   
   in) can not instruct Window to hibernate without help from Windows.   
      
   Are you also not including more info...   
     e.g. the device is a laptop with a battery, not desktop; the laptop's   
   Power option for 'On Battery is configured to 'Hibernate', the device is   
   a desktop with the UPS battery recognized by Windows Power Options and   
   that battery in Power Options is configured to 'Hibernate' and/or your   
   device is using UP@ or 3rd party software to force Windows to turn on   
   hibernation when Windows hibernation is completely disabled  and lacking   
   a 'On Battery = Hibernate' setting(i.e. an extremely rare possibility).
