I got Ubuntu 14.04 installed on Dell Inspiron 5521. When I close the lid it falls asleep. Often when later I pass by it I notice that its LEDs indicate it's awake. Indeed it is awaken when I check.
I double checked that mouse movements and clicks cannot wake the beast up. What else awakes it? Is enslaved by FBI or NSA?
I don't have wired LAN, and only my notebook and my smartphone in WiFi LAN.
