Detecting Battery Backup Notification

I am setting up a couple of servers for an internal beta test of a web app.
I want to implement a feature that would tell logged in users to log out
should a power failure occur (and the servers are running on UPS batteries).

Assuming I configure the Power Options so that "Notifications" are
broadcast, how do I detect those notifications in my web app? I have search
high and low for what these "Notifications" are but cannot find anything.
 
I'm reading the MSDN help now (that's always an interesting exercise isn't
it!) to figure out how to write a user space service that will listen for
power change system events.

The article was very helpful.

Thanks! I think I'm on my way to figuring this all out.

That article basically details how to use the SystemEvents.PowerModeChanged

Good to hear. I didn't find the PowerModeChanged event docs very detailed.
The article is a good adjunct.
