It depends on the mobo and the acpi tables if it works. It works on my
laptop but not on my destop for instance.

Well, if it's not the ups nor a thermal overload, I guess the obvious
solution is that some joker gave a shutdown command with a 3am time. :-)

According to shutdown(8) there should be a message in the log stating
when the system went down, who did it and why.

Or maybe there is a script that calls shutdown under some circumstances?
