So, today, I talked with a guy from a notebook store (I know him a bit), and asked him about removing and swapping the keys. He strongly advised me NOT to do it. Told me a friend of his knows how to do it (the thing is, it's easy to take the keys off, but not to put them back), but he tried already on broken laptop keyboards and failed everytime...
Now, I'm a bit clueless on what to do. I remember doing it on my mother's acer laptop (a bigger one, don't know the brand) because something was stuck under one key, and it was ok. Actually, I didn't think it would be hard to do, and it was reaaaaally easy, but now, I'm scared... :?
