Here's how to play on a laptop - for those of you who are wondering. Yes it's possible, and yes you can do just as well with it if you practice.
Your laptop most likely has a [Fn] key, you need to hold this down in order for it to register 789/uio/jkl as 789/456/123. You can use [Ctrl] instead of spacebar. If it still isn't working, check your NumLock (make sure it's off. And check your ScrollLock (make sure its off as well...)

Here you go, a mediocre performance on the laptop. Enjoy!
Koyote - Spark (142bpm)
Kim Jong Kook - Lovely (188bpm)

EDIT:
For those wondering about the windowed mode. I have no idea if it's still possible, I haven't played Audi in a very long time. Take a look around this community for help: http://www.goaudition.org (less info)
