   I don't think Hybrid Sleep is an ACPI state. There is just S3.   
      
   powercfg /a   
   The following sleep states are available on this system:   
       Standby (S3)   
       Hibernate     <=== should have labeled as S4   
       Hybrid Sleep   
       Fast Startup   
      
   The following sleep states are not available on this system:   
       Standby (S1)   
           The system firmware does not support this standby state.   
      
       Standby (S2)   
           The system firmware does not support this standby state.   
      
       Standby (S0 Low Power Idle)   
           The system firmware does not support this standby state.   
      
   Nothing in a menu, hints at whether Sleep or Hybrid Sleep   
   is about to be used when Sleep is selected. You'd just have   
   to watch the disk LED to figure it out.
