Usually, a momentary press of the power button signals the operating
system to begin a shutdown (not a reboot), and a long press forces a
hardware power-off.

In the past, I've had one or two PCs which will not power-down when
commanded by the OS, they'll reboot.  GRUB has two (or more?) variations
of the halt command, so you can kill the PC from the grub boot menu, if
desired (such as when you've accidentally rebooted instead of shutdown,
and you want to abort the restart).  And I seem to recall putting a
parameter on the kernel line, to make Linux handle shutdowns
differently.

It can also depend on whether the motherboard is using APM or ACPI.

George Orwell's '1984' was supposed to be a warning against tyranny, not
a set of instructions for supposedly democratic governments.
