Half of Keyboard not working after water spill
I have a MacBook (late 2009, I believe) model# A1342. After a small water spill, a portion of the keyboard stopped working. I'd say about half the keys do nothing, and it behaves as though the Shift key is constantly pressed. Everything else about the system works perfectly, and I can still use it if I plug in an external USB mouse & keyboard.
I am guessing the only option for repair is to replace the keyboard, but I wanted to find out for sure before I go ahead and do that. Are there any other components that could have been damaged to cause this issue?
If I do have to replace the keyboard, what part do I need and is there a good guide on how to do it somewhere?
Any help at all will be much appreciated!
Is this a good question?
