MacBook Pro 13 2015 no wifi, keyboard nor trackpad working

Hello Everyone,

I’m a long time follower of this amazing web site. I work in IT and sometimes I like to repair (mostly replacements) when mac’s gone wrong.

Right now I have a MacBook Pro 13” Early 2015 that doesn’t recognize WiFi card, and also keyboard and trackpad don’t work. Only power button works from keyboard.

I bough a new AirPort card and a keyboard/trackpad flex after finding other people successfully made them work after replacing that flex, but in my case they all continue without working. I also reset the SMC/PRAM thing.

Any ideas or suggestions?

I would first try reseating the I/O board cable and then I would replace it MacBook Pro 13" Retina (Late 2013-Early 2015) I/O Board Data Cable Also inspect the I/O board for any corrosion or staining. If the USB lines from the I/O board are messed up they will effect your keyboard, Trackpad and Bluetooth.

Thanks @danj , it makes sense if the IO board cable is faulty wifi/BT card wont work, but when I plug any usb device belonging to same IO board they work. Is that possible?


Ah! Yes this doesn't seem likely does it ... Plug in a USB power meter like this one USB Mini Voltmeter into your USB ports I think you'll find the system is not offering out power to the port. This is the issue at hand, a bad connection or power logic. When you plug in a powered USB device it will work as the data lines are still working.


I plugged an external HDD powered by USB and it worked good. Do you still think I should get that cable? I opened the mac and no corrsion or anything unusual on the IO board


Well I guess if the I/O cable doesn't work then you need a new I/O board or logic board. Ouch!

I would place the bet still, lets just replace the cable hoping it fixes things as its the cheaper direction.


Alright, I'll let you know, thanks for your help
