I was replacing the thermal paste and something mustve happened to the keyboard connector strip cause the keyboard is now 80% working. Keys like "y", space, "h", "n" just random keys are not working. Others are. Is there a way to replace the keyboard without replacing the entire top case? I'm reading that you cant but couldnt' find a clear answer. There are keyboards for sale for the macbook on ebay for this particular model # so I'm not sure. This sucks........... I just got this laptop It's the mid-2010 white macbook btw. at least the thermal paste worked, its running really cool now.
