This started quite a while ago, but I always thought it did some updates or something - until I realized that I disabled the instant-on feature many months ago.
The noise it's makin sounds like it's trying to read smth from a disk but fails (it's the all digital edition so it's not possible for it to read any physical games).
The noise is only there when it's turned off. It usually makes a few beeps and then goes back to beeing silent (except today where it went on for over 10, maybe even 15-20 minutes.)
Does anyone have an idea what's causing this?
