Actually, the power switch on modern computers doesn't switch it off
immediately. It gives a signal to the operating system to shut down. I
think this is done with ACPI, but I'm not an expert in this matter.
Windows as well as Linux respond to this signal with a proper shutdown
sequence. You can even configure that it doesn't shutdown, but goes to
suspend or standby.
Only when you press the power button longer than a couple of seconds, then
you really cut the power like in the old days.

All of this may of course be irrelevant for older computers that don't
support ACPI.
