# There have been a few instances lately where I've reached forward to the adjust the screen angle on the MacBook and it's just gone black.
I was starting to worry it had some kind of a problem, perhaps a loose connection, until I realised it only happened when I did it left handed with my arm along the side of the computer.
The magnet in the Watch strap obviously lines up perfectly with the one in the MacBook which detects when the screen is closed.
Panic over!
