Your best bet is google, to find discussion threads where others are using this same laptop. The 'lspci' output is what you're after.

You could also find a retail store that sells this model, and boot up a live CD in it, to capture the lspci output yourself.
Laptops are strange machines, lots of non-standard and proprietary stuff that you don't see on the desktop. You don't want to buy one unless you know for sure all the hardware will work for you. Another suggestion is to call the manufacturer and ask them for the full detailed specifications.
