Modern Standby includes a Disconnected Standby mode. It never actually enters S3 sleep, because Windows assumes S0 sleep support means no S3 sleep support. Disconnected Standby might use a little less power than Connected Standby, but the computer is still subject to the same wakeups and wakelocks.
If you can't get the PC to stay asleep I wonder if disconnecting it from the internet will keep it asleep?
