Product Details
Is your Mid 2012 13-inch MacBook Air not charging, or has its left USB port or headphone jack stopped working? The MagSafe 2 port, USB port and headphone jack all sit on one small I/O board (also called the IO board), so a new I/O board is usually the repair you need.
This board fits the 13-inch MacBook Air A1466 from Mid 2012 only. Got a Mid 2013 to 2017 Air? It uses the 2013-2017 MacBook Air 13" I/O board.
Part Includes:
- 1x I/O board with MagSafe 2 port, USB 3 port and headphone jack
- 12 Month Warranty
Please Note
Does NOT fit the 2013-2017 MacBook Air 13" A1466, even though it has the same A-number. Check the year in About This Mac.
Please Note
Carries the MagSafe 2 port, one USB 3 port and the headphone jack. Reuse your own I/O cable, as the 2013-2017 cable is a different part.
Please Note
The battery stays in and is only unplugged. The fan comes out to reach the board.

- Always power down your device prior to working on it
- The 10 P5 bottom case screws are two lengths. Track your screws on a magnetic work mat or tape them to a drawing of your laptop, as several screws look alike but are different lengths
- Unplug the battery by pulling its connector tab towards the front edge, never straight up
- Pull the camera cable parallel to the board towards the hinge with a spudger. Lifting it can break the socket off the logic board
- The logic board end of the I/O cable sits in a deep socket. Walk it out by levering alternate sides
- The fan and the I/O board are held by T5 screws
