Introduction

Use this guide to replace the I/O board containing a USB 3.0 port, HDMI port, and SDXC card reader.

It's not strictly necessary to remove the SSD in order to replace the I/O board, but doing so provides some additional clearance to make this process easier. If you are comfortable replacing the I/O board without removing the SSD, feel free to skip the SSD steps.

  • Remove the following pentalobe screws securing the lower case to the MacBook Pro:

    • Eight 3.1 mm

    • Two 2.3 mm

The number of screws listed here is wrong on my model. I had four of the smaller size.

Just to add to my comment above (I can't edit it because it's anonymous), my MacBook Pro is a mid-2015 15in model 2.8GHz (A1398; EMC2881). For the bottom case it uses six 3.1mm screws, and four 2.3mm screws at the clutch/hinge side of the MacBook Pro. I tried using a 3.1mm screw at the clutch/hinge end, as described in the main article, and they don't fit. It has to be four 2.3mm screws.

Removing the screw will void warranty?

Gently lift each side of the battery connector to pry the connector out of its socket on the logic board. Bend the connector back toward the battery, ensuring that the battery connector doesn't accidentally make contact with the logic board.

Disconnect the three AirPort antenna cable connectors from their sockets on the AirPort board and bend them up and out of the way. Be careful to pry against the connector, and not the cable or socket. Be careful to pry against the connector, and not the cable or socket.

Lift the fan and push it gently towards the back edge of the MacBook to free the fan cable from its socket. The fan cable may be adhered to the logic board—to avoid tearing the cable, gently peel it up while lifting the fan.

Lift the end of the SSD up enough to pass over the speaker directly behind it. Do not lift the SSD too high, or you could damage the contacts or socket. Pull the SSD straight out of its socket on the logic board.

Use the point of a spudger to flip up the locking mechanism on the I/O board connector. Flip the spudger around and use the flat end to slide the I/O cable out of the connector. Push on the opened locking mechanism for an easy way to slide the I/O cable out of the connector. This could help prevent accidental damage to the cable or connector contacts.
