In this post I will guide you through the keyboard replacement procedure on a liquid damaged 11″ or 13″ MacBook Air.
In my case a little bit of water was spilled on the lower right corner. After that some of the keys stopped working but the rest of the laptop worked just fine. I was able to use it with an external USB keyboard.
My MacBook Pro hard drive was running out of space. I decided to replace the hard drive with a larger one and clone the OS. I used built in Disk Utility to clone the old hard drive to the new one and the clone process was done without errors.
After cloning Mac OS X to the new hard drive, I found that now my MacBook Pro boots much slower than before but after it boots up everything works as good as before.
If you experience the same problem here’s the solution.
Sometimes, when you troubleshoot a MacBook, MacBook Pro or MacBook Air problem you need to turn it on without using the power button. Is it possible? Yes, it is!
In these laptops (unibody style) the power button is permanently attached to the keyboard. Basically, it’s a part of the keyboard as you can see on the following picture.
If the keyboard failed (let’s say you spilled liquid on it) and the power button stopped working there is a workaround for turning it on.
You cannot use this method to turn on your MBP on a daily basis but it is a good troubleshooting technique. It might help to figure our if the motherboard still works even though the computer doesn’t turn on when you push on the power button.
You can turn it on by shorting the power-on pads with a small flathead screwdriver for a couple of seconds. The power-on pads located on the motherboard. In order to access them you’ll have to remove the bottom cover and it’s very easy.
