The PowerNotify.exe is a small application without any user interface that simply queries
device's power states and performs an configurable action.

Usefull if you want to save battery power.

Regarding memory resources, it is much more efficient than MortScript. Regarding CPU resources, 
it is also better since it doesn't poll the external power status every second. It just gets 
notified whenever the status changes. In addition it can handle some more power notifications, 
e.g. battery level low or critical.
