    My 13" MBP was just sitting on the table on but idle with the lid closed. Suddenly, the fan goes crazy at 6200 rpm for no apparent reason. Had to shut down and re boot. I have no idea why this occurred. Any ideas as to why this happened?

    I would recommend launching Activity Monitor app in the Applications>Utilities folder. Check the Activity Monitor CPU tab to see if there is a process that might be making high use of the CPU and causing the fans to spin up to handle the heat. If there is not runaway processes then there might be a hardware sensor problem. You might search for Mac apps to show temperatures. I use iStat Menus to monitor my Mac. You could also check the App Store for temperature monitoring apps to see what the sensors show.

    Just a rogue process it happens sometimes, if you continue to have problems then you'll need to track it down and sort it out but a one off is usually fixed with a shutdown.
