Ps4 doesn't go into sleep mode?

If I want to switch my ps4 to sleep mode then it says that it is going into sleep mode, it makes a beep and then it stands there or the light flashes all the time.

First check whether it is set to an automatic sleep mode or switch-off mode.

I just found the solution, and it was set to never, so it never goes in automatically, just manually, but it was up to me that I had auto upload data.
