Do you have "halt: unable to iterate IDE devices: no such files or directory" when you try to shutdown?(In my case,it told me "networkmanager" error.When I entry recovery mode,type "halt",showing "halt: unable to iterate IDE devices: no such files or directory") You can try to open terminal :
gksudo gedit /etc/modules Then add a line: apm power_off=1 Thx to "Confused57" of forum.ubuntu.org.
