My Mackbook Air 2008 has 1 long beep code and it does not boot up.  This system has 2 GB RAM built-in on the Main Board.  Please advice.  Thanks

Hi Rohm09,

It is an EFI ROM update in progress. Here is a link to what the beeps mean: http://support.apple.com/kb/HT5860?viewlocale=en_US

Much thanks, MacGuy47.  Now I can't even attempt to upgrade the EFI.  My battery doesn't hold charge any more.  I have power adapter but I could not proceed farther.

Thanks Rohm09. I will have to hit the object button because it will stop what has been put in motion. I'm more concerned about your problem though. Do you have all the information on your HD backed up?
