Ethernet port being used while PC is turned off? (lemmy.ml)

Greetings! So recently, i spent a few hours coding software. After i was done and i shut off my pc, i noticed both of the ethernet lights were on and blinking. Does this mean that Microsoft is sending data to their servers before the PC fully shuts off? I am scared that this might be the thing it does. How can i get rid of this issue? I have no idea if it's related to Windows or the PC itself.

sure it depends on the design, but no standards-compliant non-PoE Ethernet design is going to light up an LED, it barely uses 1 volt.

I think driver examples from the Linux kernel are very convincing evidence that the lights can be controlled entirely by software, but I'm interested to see any possible specific port designs where that isn't true.

I was not refuting that, yes drivers can control the LED since forever. The original comment was "the link light is powered by the switch", which I'm saying is not possible. An ethernet switch (assuming it's not PoE) cannot directly power an LED on a network adapter in your PC let alone the rest of it, that's all I'm saying.
