Chosen Solution
I’m having problems with my Macbook. There was an accident and my daughter dropped some water on it. The issue is that luckily it was off and did not damage the motherboard (I’m using it to do this posting). But unfortunately my keyboard and trackpad have stopped working. I tried to change the flat cable of the trackpad as some people have suggested elsewhere, tried cleaning the contacts and nothing solved my problem. Curiously the keyboard works to power the Macbook, after all the Power key is part of the keyboard and the keyboard also works for SMC reset, but when I enter the system nothing works and in the system settings the trackpad becomes non-existent. Anyone have any tips on any solution? PS: External USB or bluetooth keyboard/mouse works fine. Thanks
I’m surprised you managed to get the cable out! Its takes a lot of effort to remove the battery to get to it. Depending on how you approach it your battery may need replacing as prying on it can damage it! Hopefully you used this guide: MacBook Pro 15" Retina Display Early 2013 Battery Replacement. If you didn’t use the techniques they outline I would strongly recommend you replace the battery as LiOn batteries can have an explosive fire if damaged. The newer Touchpad models which have the keyboard connected to it and the combined signals are forwarded over the same cable to the logic board. Its this cable which can go bad it also goes across the top of the battery as it rubs against the cover and the grit that collects on the cover. In all of the systems a swollen battery can press on the cables, keyboard or trackpad which can cause them to fail. Sadly, you didn’t address the root problem. In your system the keyboard & trackpad have independent connections to the logic board so either both are damaged or the circuitry on the logic board for the internal keyboard & trackpad is damaged. I’m suspecting the logic board is where your problem is. At this point you’ll need to do a detailed inspection of both sides of the logic board looking for any staining or burnt parts. even still repairing logic board can be tricky depending on what you find. Frankly, this type of repair is something I pass over to someone who does it day to day.
