Repair Macbook Air No Audio/Sound Device Detected



I have an old mac machine, Macbook Air mid 2013 run on Sierra Mac OSX. It has no sound/audio device detected so i can not hear sounds or record audio. Replacing “I/O Board Power Audio Board, USB, DC Jack” fix the problem. I ordered replacement part on aliexpress (audio Port + Cable) for only $18 free shipping.
At the end of videos you can see the time resetted to old date because battery removal, i have to set date and time manually.
