kazuma, check your bios and see if any of the voltages are set to anything other than Auto.Apple Menu -> Sleep.
When I forced the sleep, the monitor (P2770HD), I felt the presence of "No Signal", but the computer is always on and the fans continue to run smoothly. Before further update to 10.8.2, what to speak of a few megabit (26MB), everything worked great.
