Always-On/Always-Connected (AOAC) is a standby state when explicitly supported by hardware. If the network connection is not in use, the system turns off the Network Interface Card (NIC). It then pretends that the NIC is still connected, and the system periodically wakes
up to renew its IP address. When woken, if there is an incoming notification for that system, then the Microsoft notification service from a remote
server sends a matching packet to the system, waking it.
While BSoD fatal stop errors are identified by Microsoft Windows, they are often caused by
non-Microsoft applications, drivers and hardware issues.
