Both XFCE and Upower unable to execute the "Hybrid-Sleep"

Hello, From some quite time I'm trying to enable the hybrid-sleep feature whenever battery level hit the critical threshold. Despite the fact that by running the command from the console it works perfectly, it doesn't using Upower or Xfce-power-manager. In the better cases I just obtain the Hibernate of the system. Is there anybody having a solution for this? I would like to both suspend and saving on disk my windows and tasks opened if the battery drops to critical charge. Thanks for your attention.
