Why is my keyboard/trackpad not working?
I bought my Macbook Air in September of 2011 new from the Apple store. My trackpad was replaced by Apple in September of 2012 as it gradually began to become unresponsive. Since the repair, I haven't experienced any other problems. The unresponsive trackpad was the only problem I've run into with this Mac.
After some brief surfing around this morning, I went to work with my MacBook running fine as usual. After coming home, my keyboard and trackpad are both unresponsive. What's a bit more unsettling is that, in the System Preferences, it's not even recognizing a trackpad as being connected.
After doing some searching around, I've found that some people ran into this issue with MacBook Pros, and it was because of a ribbon that had become loose underneath the battery. I'm wondering if it's possibly the same problem for me with my MacBook Air. I hadn't read about anyone with an Air experiencing the same problem.
Any help would be appreciated.I would love to get my Air working so I don't have to constantly use my external keyboard/mouse.
Edit: The only key that works on the keyboard is the power button.
