Macbook doesn't go to sleep when closing lid?

Question

macbook

Until recently, everything was fine, but now the macbook has stopped going into sleep mode when the lid is closed. I noticed only now, since lately I have been putting the system into sleep mode using the active corner. And then suddenly I decided to put the lid into sleep mode, and the monitor (external) first went out for a couple of seconds, then the picture appeared again, that is, the computer did not even go into sleep mode.

Answer 1

So it's not a bug, it's a feature. if an external monitor is connected to the macbook, it should not go into sleep mode when the lid is closed. perfectly normal behavior, as far as I remember it always has been.
