The problem occurs both in Fedora 17 and Ubuntu 12.04. Sometimes there is a clean shutdown but most of the times it doesn't power-off the system. Keyboard and network card (green light indication on the ADSL router/modem for this wired line turns orange) is turned off, but cpu fans, power and hdd led's are in ON condition. I have to manually (long) press the power button to turn off completely.
