I've got a machine with an M2N-MX mobo. This thing doesn't seem to allow
power management under XP! Even basic things like Standby and Hibernate
are missing. When you press the "Turn Off Computer" button, the only
options are Restart and Turn Off; Standby is greyed out, and Hibernate
isn't even presented as an option in Power Management properties.

I've flashed it to the latest available AMI-BIOS (0704). I've set the
ACPI support from ACPI 1.0 to 2.0 to 3.0 and back down, nothing has
fixed the issue.

I've also got it running under Ubuntu 7.04 64-bit, and it's the same
issues there. Under it, the temperature sensor utilities tell me "no
sensors found". But interestingly the AMD Cool'n'Quiet continues to
work, I see the two processor cores (Athlon X2 4600+) changing speeds up
and down independently like normal.

I have another system with an Asus mobo, M2NPV-VM, with the same basic
chipset (Nforce 430), but with a Phoenix BIOS which is working perfectly.

Any ideas?

If you go to Device Manager, and check the properties of "Computer",
does it say "Standard PC" or "ACPI Multiprocesssor PC" ? If the HAL
is "Standard PC", that would explain the limited options to turn off
the computer.

If you did a clean install, did you get an error message, about some
problem with ACPI ? Like "not compliant" ? I had that happen with one
Asus BIOS, where when I tried to install, the ACPI tables from the BIOS,
were not to the OS installer's liking. I ended up with a "Standard PC"
as a result, and had to endure that "it is safe to turn off your PC"
crap.

Once I tried a later version of the BIOS, then I could install an
ACPI HAL, as normal.

Some HAL changes are easy. Changing from one flavor of ACPI HAL
to another, is a "driver change". But I suspect that escaping from
"Standard PC" is not going to be so easy.

During an OS install, you can press F5 to force a HAL. Normally
I think it would select an ACPI HAL without any coaching, if
the ingredients are there.

Also, when using Ubuntu, did you examine the log messages that
occur during boot ? Were there any complaints about the ACPI tables
passed by the BIOS ? You might get more useful info from Linux, than
from Windows, if there is a problem.

There are also a couple of reports here, of weirdness with that
motherboard. One guy could not get both cores to be recognized
when using a dual core processor. (Make sure you report your problem
to Asus tech support, so maybe in three months time, you'll see
a new BIOS release with a fix. Asus is probably not monitoring
these forums, looking for trouble.)
