WARNING! Keep those magnets away from that small area between your USB and Headphone port on your MacBook Air!
That’s right. No matter how tempting it is, apparently placing a magnet on the left side of a late 2010 MacBook Air, right between the USB port and the headphone jack, will cause the WiFi and screen to turn off. So far Apple has not provided a solution for users who need to store their magnets there, and Apple PR has not returned our calls on this important matter.
