I think there is a major misconception:
halt (or shutdown -h) will halt your PC whereas poweroff (or shutdown -P) will power it off.
The shutdown -h behavior has changed since Natty, but according to the man page both variants are valid.
Easy fix: Use shutdown -P and your system should power off again.
