Hi everyone, This is my first post, so don't yell at me if this is the wrong spot to post it. Anyway, I bought my first Apple computer, a 12" PowerBook at the very end of December last year, and I'm having an intermittent but very annoying problem. My spacebar key has started to make a squeaking type noise. I don't know how else to describe it but it's quite irritating. Does anyone know what I can do about this? I know it seems trivial, but it really bothers me. Is this a common problem? Thanks for any input anyone can offer!
