When you see the Activation Lock screen, it is most likely that your device is restored and set up as a new one. The therm “watchdog” indicates the function of the circuit: it is used to prevent that the system hang-ups in case of a runaway code or when an operation has run longer than expected, and it has been designed to be used in such applications where the device is put in a far or not easily accessible location and where a quick and indipendent action is required. However not many desktops have hardware watchdogs, so the kernel provides a software version.
