prejudice I noticed that I do not work 4 keys on the keyboard of my MacBook unibody white .. I wanted to ask if anyone knows where I can find the directions to remove the keyboard and repair the circuit tracks? I tried to look for new keyboards, but I have to buy the whole piece of the keyboard and costs $ 190 on average
If keys aren’t working, cleaning the tracks will not resolve the issue, it will need replacing. On the plastic unibody (A1342) the keyboard is glued in with a black plate glued behind it. I have only replaced one, where I fitted an A1278 keyboard instead (couldn’t get A1342 keyboard), but it was a nightmare to do and from then on I have replaced the palmrest. You have to glue the new keyboard in, and glue the black surround back on (otherwise the keyboard is not nice to type on, unstable), and initially pulling it apart is very difficult to do, since it is glued to the plastic casing. I would recommend swapping the whole palmrest since it is a lot easier, I can get them from my supplier with minor scratches for 85$, best to get them used from China or eBay.
