Laptop goes to hibernation mode despite configuration saying otherwise

[Jens Herrmann]

Since the upgrade to 13.10 two days ago my laptop goes into hibernation mode when I close the lid. This was not the case before. This is despite my XFCE4 configuration 'On AC' 'Actions' 'When laptop lid is closed' in Settings/Settings Manager/Power Manager says 'Nothing'.
