Product Details
Has the USB port on the right side of your MacBook Pro 13" Retina stopped working, does the HDMI port give no picture, or will the SD card slot no longer read cards? All three sit on one small right-hand I/O board (also called the IO board or daughter board), so a new I/O board is usually the repair you need.
This board fits the 13-inch Retina MacBook Pro A1502 from Early 2015 only. It joins the logic board through the A1502 I/O board flex cable, which we also stock. Charging problem instead? The MagSafe 2 port is on the A1502 MagSafe 2 DC-in board.
Part Includes:
- 1x Right I/O board with USB 3 port, HDMI port and SD card slot
- 12 Month Warranty
Please Note
Does NOT fit the Late 2013 or Mid 2014 MacBook Pro 13" A1502, which use a different board, or the A1425. Check About This Mac says Early 2015.
Please Note
Your Wi-Fi and Bluetooth (AirPort) card plugs into this board. It is not included, so move yours across from the old board.
Please Note
The heat sink and fan come out to reach the board. The battery is only unplugged.

Here are some helpful tips to assist you in completing a safe repair on your device. If you are unsure of something or have any questions, please feel free to contact us either by phone (0508 IGADGET) or by email
- Always power down your device prior to working on it
- The 10 P5 bottom case screws are two lengths, with the two short 2.3 mm screws at the hinge end. 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
- The heat sink comes off, so clean off the old thermal paste and apply fresh paste before refitting it
- The three AirPort antenna plugs are fragile. Lift each one straight up by its head, never by the cable. On refit, the long-sleeve cable goes in the centre socket, the short-sleeve cable next to the screw and the bare cable next to the fan
- The I/O cable bracket and the I/O board are held by T5 screws, plus one 3.5 mm T8 standoff. Unplug the I/O cable at both ends with a spudger
- Move the AirPort card across: one 2.7 mm T5 screw, then pull it straight out of its socket with tweezers
- Check the old board is printed 820-00012. The Late 2013 and Mid 2014 board (820-3539-A) looks similar but is a different part
