Hi everyone, I have a Dell Latitude D600 laptop. Recently I had what seems to be a common problem with this particular model in that it would not properly boot up. I sent it in to one of my mother's coworkers that works with IT, and she got it up and running again. But when I got it back, I found that the keyboard was making this strange click-like sound every time I hit a key. I checked, and it's not coming through the speakers, but from some other outlet. Any ideas/answers?
