Closed screen (closed lid) sensor

Hello,

I am new on this forum!

I have a question about my macbook pro:
When I close the screen, it don't suspend my macbook.

I can suspend it by going to the apple menu but not when I close the screen.

The screen don't even shut down when I close it.

I think it's a problem with the sensor that detects when the screen is closed or opened.

Can anybody help me about that?

Thanks

take it to apple and let them fix it if it still under warranty, seems like a locking issue or sensor problem..

How does the MacBook sense if the lid is closed? There doesn't seem to be a mechanical switch as on my last laptop.

Probably a magnetic sensor? Where are the magnets located, anyway?

Try in energy savings see of you can see anything.
