Shane,
Go into your Device Manger through Control Panel/System. Click the "+" sign next to "Sound..." and you should see what your laptop has as far as a sound chip goes.
If you're looking to find a nice setup as far as speakers go, surround sound included, you'll have to know if your chip supports it...or it's a waste.
If you have an audio program installed, you can find out there as well, by opening that program and seeing what the default hardware is on your laptop for playback/recording.
Also, within that program, you should be able to note in the speaker testing aspect of the program, whether or not it has a test for surround sound speakers...as well as a sub woofer.
Along with this info...and a budget...I'm sure someone will be able to make a better recommendation to you, other than..."yeah...these are great...you should try these!"
