I want to add APCI notification(OR power management) to my UPS management software.

Hi:
everyone, I already have an ups management system, that only is based
application layer,
has no connection with ACPI of system layer.
When it detects ac failed, OR battery is weak, management system itself will
decide to do something.
Now, I want send a notification to ACPI of OS while the events happen.
And let ACPI chooses to do something at next steps.
I have already looked into power management of microsoft, But i dont know
how to implement this in details.
I need make a DDK driver to finish it? OR only some application layer
functions are enough.
Thank in advance.

I cannot understand how ACPI is related to UPS, and what kind of notification you're talking about.

Do you want to put the machine to standby or hibernate?

Yes, you are right.
I want to have operation system own make a choice(hibernate OR standby
,suspend).
Just like system has a battery, Once ac fail,, OR battery is weak, OS will
switch to hibernation ,OR standby status
in order to save power.

I only need to notify OS that now it need to switch into save power
mode.(hibernation)

I wonder if it is able to be implemented with driver OR application.

Addtionally,
I can get power status of UPS via data communication.
machine is powered by the UPS.
SO you may consider the ups as a battery of machine.
Once power status of UPS is changed,
I need to notify system switch into a save power mode.

I think that MS-provided UPS service can do this since NT 3.1

Sorry.
My ups.exe can not work
I am not sure that it can do this job.
But i think that i need move this function into my software.
I mean only notify ACPI of system.
I never do other extra job. only send notification to ACPI.
What you can do are to notification to ACPI ,
and It own decide what it should do.

even, i try to make a virtual battery, just like laptop with a battery in
right-bottom tray.
while switch to back-out mode(ac fail),,ACPI will work at once warning
mesage appear,
CPU,OR other hardware devices enters save power mode(S0~S3 level)
at last system will enter suspend,even hibernation.

But i want to try this with application layer first.
