Hello, my 80GB first gen MBA stopped working yesterday. No display or chimes. I press the start button and the little light on the front comes on for a moment, then you can hear a "click" and the light goes off. If I hold down the start button continually, the light comes on with a rapid blink/pulse (too quick to count) and then clicks off again. I cannot boot the machine off the superdrive. I tried all the reset options at http://support.apple.com/kb/TS1365?viewlocale=en_US Would anyone know if this is symptomatic of harddrive vs. logic board failure? If logic board, then the cost is simply not worth it. If it is a hard drive, I can (and have) replaced these myself...even though I understand the MBA is more difficult. Any help or pointers would be much appreciated. Thanks!
