30 minutes - 1 hour
I lend my Mac Air, so a friend of mine could play some musics in a bigger speaker. But, the cable that he used was broken and a tiny piece of the P2 plug stuck in the P2 Jack
So I went to iFixIt to find how can I repair my P2 Jack, because I wasn't able to hear my headphone *.*. I tried with super glue, bic pens and everything that I found on the YouTube but nothing worked. So I decided to repair myself. I bought the I/O board and when I was repair my Mac I was so nervous and shaking hands, because Macbooks in my country are very expensive =x. But I did it! Finally my Mac is working good again xD
Just follow the steps with patience. You'll be well.
