Re: how to turn off devices that monitor sensors

[Robert Elz <kre%munnari.OZ.AU@localhost>]

You might try "boot -2 netbsd" to disable ACPI completely,
in which case NetBSD would not be able to request ACPI S5 state
to shut down and power off (would need to use older BIOS
interfaces).

If your system is an older one (HP model numbers mean nothing
to me) then it shoukd work OK without ACPI.

You could also confirm whether other OS's are able to
power off that particular system (the test needs to be
of that exact system, as minor variations like what BIOS
rev is installed, what other hardware, and the BIOS
config all could alter the results.  Installing other
systems should not be needed, "live" cd/dvd boots (or
USB stick) should be sufficient to test this.

But testing NetBSD with ACPI disabled first is the quick
test to perform.
