I have a 2010 Macbook White Unibody that is having some weird keyboard issues. Certain keys will not work, ex: 1, and B. Some keys do other things, like everytime I hit return it creates a [ bracket. I wiped the computer and started fresh to diagnose it. I opened up and checked the battery to see if it was bulging and it was seemingly fine. I ran apple hardware test and it said no issues. By the way, when I plug in a USB keyboard, it is fine. Any suggestions would be greatly appreciated it. Thanks!
