This may have already been answered but here are some more points.
1) Laptop LCD screens often run at 60Hz. My game on my desktop (of 85Hz) is silky smooth. Yet, when I run it on the laptop, it seems to be running in slow motion.
However, when I connect an external monitor into the laptop, I can bump the refresh to 85Hz and it runs smooth on the laptop! So, that's something to remember.
2) As said before, most laptop harddrives run at 4200rpms. Very slow. And the busses are really slow too.
Try connecting an external monitor to the laptop and making it the primary display for testing (turning off the LCD).
Be sure to increase the refresh to 75Hz or more.
