I don't use the laptops internal speakers. I use earbuds or wired headphones. So, it wasn't until much later that I discovered the MacBook Air's internal speakers were not working. I took it to the apple store, and they came back with pictures of water damage and corrosion and told me that it would be $799 to fix it, or I could get a new one for $999. I just bought It refurbished six months ago so I tried to go back to the vendor APLCOMO. But it was after the 90-day warranty so I'm out the money. buyer beware. Have you purchase checked out before the warranty is up or your stuck with it. And don't take this vendors word that your item has been fully checked out.
