My PB was working fine this morning... a few minutes ago, I went to use it, and the keyboard doesn't work anymore. Some keys type the wrong thing ("a" types "*"), and some don't do anything at all. This happened out of nowhere. It's a rev. B 12" powerbook that I've had for 8+ months with no problems whatsoever. Repairing permissions and restarting didn't help. I'm typing this on an external keyboard attached to the PB now, and it works fine. I'm really confused, and could use all the help you can give. Thanks!
