The PoSetSystemWakeDevice function attempts to extract a PDO from the supplied device object. If a valid PDO is found then it is added to the list of sources which contributed to waking the system from a sleep state. There is a time interval (currently 2 seconds) during which, from the completed wait/wake IRPs, the power manager attempts to build a list of system wake sources.

[in] PDEVICE_OBJECT DeviceObject
