Check if on battery power

[Cory_K]

Is there a way to check in LabVIEW (or otherwise) if a laptop is running on battery power?
The reason I would like to do this is that running on battery power would be indicative of a power outage in the field where we are testing, which would be problematic for other equipment.

Is there some function I can call in LabVIEW to check this? Or something I can call through the command prompt (Windows)?

Thanks Ravens Fan. That was exactly what I was looking for.

I just looked here for details about this dll, and this is what it says for

'ACLineStatus'

- 0 for offline

- 1 for online

So does 'offline' mean that the AC is offline, so it is running on battery?

By looking at the code, if the value =1 then it is on AC power (not =1 means on battery).  So offline means on battery.
