Serial number became unavailable and no sound
Hey everybody,
Decided to take apart my MBA to cleanup. Did everything very carefully. After put everything back my MBA works fine, even better than before, BUT serial number and sound became unavailable.
Setting of new serial number is not a huge deal, but why it was reseted? Did I damage something on a mother board?
What happened with sound? There is no startup sound, no sound in headphones, build-in speakers do not exist at all in system info.
Hope somebody can help me. Thanks in advance.
Это хороший вопрос?

Please clarify what your model is: a MacBook Air or a MacBook Pro Retina and the screen size.

You had listed MBA (MacBook Air) in your question which confused which you had.
