Is there a way (POWER IRP??, ACPI callback?) to detect a transition when a
system is running on AC to DC power?

thanks,

daniel

Check the docs for ExRegisterCallback - the callback you want is
\Callback\PowerState.

Eliyas:

thanks, this will work.

Is there a similar way to get notified when a user docks/undocks a docking
station?

thanks,

daniel
