Not starting up - 3 beeps on startup
I have a MacBook Air 13-inch, Mid 2011 (1,8 GHz Intel Core i7, Memory 4 GB 1333 MHz DDR3).
The computer is not starting up anymore. When I try to power it up, it beeps three times continuously, takes a short break, and then starts beeping again:
beep beep beep (short break) beep beep beep (short break).... and so on, repeatedly.
What could be wrong with my computer? Is there a way I could repair it on my own?
Thank you very much.
Regards,
Hugo
