So my 13" MacBook (aluminum unibody) got some windex under the keys and long story short the keyboard / top case is broken. I already tried removing the keys and cleaning with rubbing alcohol and q-tips. When I type any keys, strange symbols come up instead of letters or numbers. According to the apple store the logic case may also be broken but the laptop does turn on. I was going to replace the top case but I don't want to find out I need to replace the logic board as well after doing that, as I'd rather just spend a bit more money and get a whole new laptop. -Is there a way to know for sure if the logic case is broken? -Would I get more money selling it for parts or as it is on eBay or something of that sort? What parts would even be salvageable? (Besides the battery screen) Thanks!
