MacBook 2015: Trackpad, Keyboard AND Display not working

Hello,

I´ve got to repair a friend´s MacBook late 2015 Retina 13”.

Apple Store said the display is broken, but that definitely isn’t the case. I opened it and checked the cables for water damage (there is a minor water damage, keys are a bit sticky.

However…

The keyboard, trackpad and display doesn’t work. It won’t turn on without cheating it by removing the battery connector and plug the power supply in - then the power button works, sometimes. SMC reset is also possible. When it starts up, the display shows the Apple logo for a short time when booting up, then it stays dark, also trackpad and keyboard don’t work. I can observe it booted when I lit through the Apple Logo from behind.

It works normally with external keyboard, mouse and HDMI display. I reinstalled the OS, it seems not to be a software issue.

My suggestions are the Macbook thinks it is closed, or some power issue.

I cannot explain, why Display and Keyboard/Trackpad are faulty simultaneously, these are different cables?

Thanks for your interest. I´m hoping this is kind of a common problem.

My computer had the same issue. Try disconnecting the trackpad and turning on the computer. I did that then it booted just fine. That will disconnect the keyboard, so you will have to press the battery disconnect button then plug it in and it should turn on. I did that and it turned in and worked. I may be wrong though
