    Hi guys,

    i got macbook air and it boots up ,,,i hear the chime boot, got white screenm the caps look key lights up green, the fan works, i can hear the hard drive spinning, if i press volume up i can hear sound, the keyboard lights up, but still white screen, no apple logo, nothing at all but white screen.

    i did sms reset and pram reset but no use, still the same before.
    i tried to boot into recovery,,,,no use.
    i tried boot into safe mode by pressing shift key after the boot chime....no use.

    i got the wgite screen.

    i powered it off,,,then powered normally, still white screen, after few seconds the screen went gray, if i press any key it comes back to the same white screen.

    i opened it and and unpluged the hard drive cable, then booted it up...but there is no chime, but still white screen....


    Any ideas ???

    thanks all. :( :( :( :( :( :( :(

    This is a wild guess, but you might need to replace the hard drive cable. I got the white screen on my MBP and had the hard drive and the cable replaced a few times. I got the white screen with a "question mark folder" or sometimes an Earth icon.

    was your computer crashing a lot before this problem? try holding down option while booting, then go to disk utility, do you see your Mac HD partition?

    I bought a miniport display adapter, got it connected to my mba and to my lcd...
    turn mba on and after few seconds i got the os screen on my external lcd, although it's not in the right resolution but i still got the desktop backgroun, cant see any icons or menu (maybe the resolution is not correct, but i can't get it corrected) i can move the pointer and i see it moving...if i close the mba screen and then put an usb thumb into mba, then my external lcd is on and showing welcome screen asking for a password which i totaly can't recall....

    so, what do you think is it ?

    bad mba screen? ( although it is lightin up in white light when powering on the mba and still lighting white and turn of that light when closing the screen !!)

    or maybe it's a bad vga cable ???

    or ......or......

    so what it could be ?

    thanks for all,
