I'm not too sure. Try right clicking on My Computer and viewing Properties. If it's not on there if you go onto the Device Manager i'm sure it will say so on there.
make/brand of laptop. also do you have WinRAR (silly question i know but has to be asked) for the files. ATM im running on an Athlon AMD 1.2ghz proc w/ 1.5gb ram and i can get the 3d engine to work but its really laggy so your missing nothing.
start > run > dxdiag > display tab > approx total memory
tbh considering its a laptop with that kind of proc and ram i think your looking at 128mb integrated gfx or perhaps even a 64mb integrated. i highly doubt you have a gfx card which makes running a 3d engine pretty hard as integrated gfx doesnt have the ability to run shader models or a 3d engine. i mean it can but not very well.
