I have a network-wide pi hole and I noticed that it requested activity.windows.com, a url blocked by my pi hole, even while my pc is suspended. I pinged 10.0.0.217 and it is currently unreachable. So, somehow, windows pc’s turn on networking, phones home, and turns off even while suspended.
Creepy behavior
It got disabled one day on my 8th Gen i7 XPS. It was driving me crazy trying to figure out why it keep cooking it self alive in my backpack. It's since been demoted to house use, sleep is still useless even after many FW updates and fresh os install. That thing used to last weeks on battery just closing the lid. Now it can't make it though the night. I wish I could turn it back on in this case, my new laptop is much better about it.
