I recently get a late 2011 MacBook Air 13 inches. Since last week. I upgraded to Mountain Lion and everything was fine. Tonight I was relaxing and watching Netflix Shows which need Silverlight plugin in my Safari Browser. Then suddenly all my system crashed and the reboot sequence started. It gets back to its normal state (desktop) and tells me to send report to Apple, I did it.


Few seconds after that I tried with Chrome browser to surf the web, it says that Silverlight plugin needed to be reinstalled. And all the computer was freezed.

I turned it off by pressing power button. Then I started it again but, the screen is black, the fans are running fast and a very strange bipping is coming out from the computer, a 3 sequences bip which doesn't stop.


It's the first time I hear that kind of "strange sound" on a mac. What does it mean ? Do I have to repair ? It's not covered anymore, will it be expensive?


Thank you

    This may be a POST code indicating failed RAM. If that is the case yes it will be expensive to fix.


    Run Apple Hardware Test:




    You must remove the firmware password, if one has been set, before you can use AHT.
