I have searched the settings and can’t find any setting that allows this behavior. I have automatic updates turned off. How do I stop it from turning on randomly?
Edit: I have a disk in it and can hear it moving parts and spinning up when it turns on. It’s so weird.
For what it’s worth, this happened to me for weeks and it turned out to be having cec on + a bad hdmi cable. Our best guess is that the cable had a minor short or didn’t seat all the way and it was triggering cec to think there was a ‘plug in’ event or similar. Replacing the cable seems to have resolved it for the last month or two.
