Chosen Solution
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? Update (02/25/2020) Ok, I changed the I\O cable but still no wifi, keyboard and mouse. @dan I’ve been working this laptop all this time with an external keyboard/mouse and a USB ethernet adapter, but now I want to give it a second try to repair it, would you guys get a logic board or the I\O board instead? whats the safest route?
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.
Same computer. Same problem. Brand new Trackpad cable. Made sure it was seated properly. However, when I returned the bottom panel, it pressed on the excess trackpad cable. The pressure was enough for it to kink near the connection to the board and sever the connection. Make sure to put the metal plate on top of the trackpad cable where it connects to the Logicboard. You’ll also want to use the adhesive on the bottom of the trackpad cable to adhere it to the battery preventing it from lifting and getting pushed by the bottom panel when reattached. I hope that helps. Chris Leeds Independent Apple Specialist http://www.wellconnectedlife.com
