I just discovered that when I set my iPhone 5 on my MacBook Pro it unexpectedly goes into sleep mode on the computer. I noticed it does this when I set the iPhone on the left side of the trackpad more closer to the edge of the MacBook and then the screen goes blank and the computer goes to sleep. Once I pickup the phone it comes back on. This surprised me so I did it again and it did the same exact thing. So what exactly is causing this? What is on that side of the MacBook to make it fall into sleep mode? and could this of damaged anything? such as magnetically doing something to either the phone or the machine?
