So my MacBook Pro is fine, well sort of. A few weeks ago I lost all Trackpad and Keyboard functions. They were completely unresponsive. Then one day, POOF, everything was working fine and the problem has not returned since. Also, I noticed that my MagSafe Power Adapter has made some 'crackling' noises a couple of times. It works fine as of now. So lets say that I were to walk into my local Apple Repair Shop and tell the worker there that the MagSafe Power Adapter and the TrackPad / Keyboard are not working, even though they were. If the worker tests the computer out and sees that nothing is wrong, will they still replace the parts? My AppleCare Warranty expires in December and I am planning a trip to the shop (2 hour drive total) in November.
