Windows pc calling home (even while asleep)
(lemmy.dbzer0.com)
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
Linus explored that bug, it's not so much with recent laptops as it is with Windows sleep in general. For some god forsaken reason, if your laptop is connected to a network while plugged in and you put it to sleep, and then unplug your laptop from the power, it will burn through its battery and die. This doesn't happen if you unplug your laptop before you put it into sleep mode. My guess is that while it's plugged in, Windows thinks it's fine for it to run a bit hotter, but when you unplug it while it's in sleep mode, it doesn't realise it's not plugged in anymore and drains the battery. Idk how they have still not fixed this after many years, but it is still a problem.
