The number keys on my Macbook suddenly stopped working not long ago. Seemingly no other keys are affected. I haven't dropped the laptop, or spilled drinks on it. It's about 2 years old, and out of warranty. I mostly use it for surfing so I'm not exactly sure when it happened. I only noticed when updating it yesterday with the java update, when I could no longer enter my administrator password, so maybe it was the result of the previous update. I can use num-lock to use the numeric keypad, but obviously the numbers 7,8 and 9 are simply not possible to use. Luckily none of these numbers are used in my passwords. I followed the advice with keyboards available from the Apple site, the keyboard is set correctly (Swiss German). Obviously I'm hoping it's something simple, don't really want to resort to taking the thing apart.
