As I wrote in bug 7752 (http://bugs.archlinux.org/task/7752) some recent update has caused the "Hibernate" option to become missing from KDE's laptop applet - at least on my notebook (a Dell Inspiron 600m).
Anyone have any clue what might have caused this? (Is it an Arch bug or upstream?) How to fix it? Any more info about it at all?
Help appreciated - this is really annoying!
