My pet theory is that a lot of systems are constantly looking at what is active on the network and those pings are keeping the machine awake.
or if you meant that, computers are normally not pingable when they are asleep. net adapters only wake the computer when seeing a magic packet with their mac address in it, and it is the operating system that receives the ping request and decides to send back a ping response.
an exception is when it is set up to wake on some network traffic pattern, but few net adapters support that mode of operation
I’m not sure what you are trying to say.
I wanted to say this is not how it works:
