Our Macbook hangs on startup and doesn't boot into the desktop environment. The most notable problem is that the Macbook doesn't make the usual startup sound when we boot up. It doesn't make any sounds at all at startup. Then it hangs for a long time on the grey screen with the Apple symbol and the spinner.
We have tried to restart it several times, and most of the times it does what I wrote above, but on a couple occasions it actually showed the desktop background, but then froze. One time it showed the blue screen and then froze.
I have tried to boot into Safe Mode (holding shift) and it won't boot into safe mode either. I tried booting into Safe Mode with verbose enabled, and the few times I did it, I didn't see any errors, but it stopped once after this line:
AirPort: RSN handshake complete on en1
The other 2 times it stopped after a few lines later:
NTFS volume name , version 3.1
After seeing these lines on the verbose output it just stops.
The one thing I CAN do is boot into command line mode (holding command+s), and I can navigate through the file system via command line. I performed
fsck -f and it said there weren't any problems with the hard disk.
That is about all I know, any help would be greatly appreciated. Is there any way I can recover this computer?
