  • Don't get baited into back-and-forth insults. We are not animals.
  • Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
  • Bigotry will not be tolerated.
    • 3. Post Linux-related content
  • Including Unix and BSD.
  • Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of sudo in Windows.
  • No porn, no politics, no trolling or ragebaiting.
    • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, <loves/tolerates/hates> systemd, and wants to interject for a moment. You can stop now.

    I’m not sure what you are trying to say.

    I wanted to say this is not how it works:

    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 was saying that my theory is that this functionality is broken or being bypassed on Windows such that when it gets hit by for instance the Network Discovery or “Do you have this update already downloaded?” ping from another Windows computer it wakes up to have a chat. I meant other systems are looking for active machines and those pings are waking it up or keeping it from going to sleep. I may have chosen a bad slang since ‘ping’ is a net command.

    This theory is based on my understanding that computers don’t go all the way to sleep anymore and reenabling S3 restores normal sleeping. I included WoL because I have a machine that doesn’t have the S3 option but disabling WoL seemed to help on that one.

    yeah, now that you say that is probably most laptops in the last few years. ~~but I don't think desktops do it.~~ wrong, even my 4+ years old pc motherboard supports it according to /sys/power/mem_sleep
