This is most certainly not what you want. NSNotificationCenter is a quite generic mechanism for dispatching and receiving notifications. What you want is a object that talks to the system power management facilities and that posts something like PMMayLosePowerNotification or PMWillLosePowerNotification, which you then observe from your application. You can achieve something like this quite easily by wrapping HAL or UPower using DBusKit, which is in fact one item on my todo-list for Étoilé. Cheers, Niels
