My MacBook Air's Keyboard & Trackpad Are Not Responding
If the keyboard and trackpad of your MacBook Air have stopped responding, you may be able to fix the problem yourself. First, see if you can get them working again — at least temporarily — so you can use your computer to begin solving the problem. The problem may be caused by an ungrounded power adapter, operating system issue or firmware problem. In late 2010 Apple did release an OS X upgrade that included a solution for this problem in its portable computers. If these do not fix the issue, you may have to take your MacBook Air to a certified Apple technician for repair.

Unplug the power adapter from the MacBook Air. Try the trackpad and keyboard again. If they now work, verify that your power adapter is connected to a three-pronged outlet with a ground. If one is not available, rest your hand on the palm rest whenever using the computer while it is plugged in at this location.
