fedora 23 Shutdonw problem

[miguel]

In gnome sessión when i shutdonw my system from power menú or from root
terminal "halt" my system turn off the screen and never shutdown. The
fan is always running and i have to unplug from the wall or turn of
from supply power. 
But if I try to power off from gdm ( no login yet) always shutdown
corretly.
Sorry for my english.
I can't see nothing when I run "journalctl" about failiure.
