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
Don’t forget the added feature of your laptop overheating and crashing when you put it into your backpack.
Or my personal favorite is when it doesn’t overheat and crash it drains 20% of it’s battery in 15 minutes then goes into hibernation.
