Closed lid restarts MacBook Pro
Each time I close my lid to my MacBook Pro, after about 3 to 5 minutes it restarts. It turns off then turns back on. I know because I hear Apple startup sound. Why does it do this and how can I stop it from restarting when I close my lid? I want to get it back to "normal" (closing the lid and it sleeps not restarts). Thank you for your help.
