That sounds like a hardware (or at most firmware) problem rather than
any kind of software issue.  On all my laptops, keeping the power button
pressed for 4-6s is enough to force a hard power-down.  And this seems
to be handled at a low-enough level that it's pretty much always worked,
even when the kernel is completely borked.
