I did the update and while restarting mine laptop failed with something i could not understand, so i restarted it now i hear is only beeps and nothing on the screen. Is there anyway to get it back i am going today to apple store and see if they could do something. Is it like i damaged mine logic board. Is it reparable I am getting too much nervous. Sorry for reposting from News Section. But i got no response from there. If its inappropriate Mods Please delete this thread.
