    I open my MacBook Air yesterday to check and clean the internal parts since I'm experiencing random restarts recently. Upon opening my MacBook Air after cleaning, I noticed that my MacBook Air serial number is not identified on ABOUT THIS MAC menu and also in system report. I did not change any internal parts, I just wipe out the dust inside. Can this be bring back?

    I think I've read a similar problem like this before in a MacRumors forum. It had something to do with an OSX update or a logic board replacement. Their solution to this is to bring it to your nearest service center and have it serialized.

    Sorry I failed to mention that the service center failed to put the serial number when the logic board was replaced.

    Here's the quote from the thread:

    You need a serializer. It sounds like your logic board has been replaced and the Genius just forget to serialize it. Take it to an Apple store and they can fix that pretty quick.

    But a reset would be the first thing to do to try solve the problem :)

    If the replacement logic board is from Apple, serial number would appear but it its from another used computer, no serial number :)

    hm, i somehow don't get that--how can a replacement logic board not be from apple? even second-hand ones would have been manufactured by apple.

    Problem solved. I download this free tool Blank Board Serialiser.. followed step by step procedure and after reboot, my serial number is back again.
