Vaio VGN-FS 790, the seller swindle ???

I just get a VAIO VGN- FS790 SonyUSA from a seller in Vietnam, prize 1540$, the kind of "Built to Order" with
Intel Pentium M 740 1.73GHz
(Sonoma, 2MB L2, 533Mhz FSB, Intel 915GM )
512/1024 MB RAM, 80 GB Hard Drive, 15.4 WideXGA XBRITE, DVD±RW Double Layer.
When receiving it configure like above. But the problem is that on the configuration label sticking outside the box writing
"Intel Pentium M 740 1.73GHz
(Sonoma, 2MB L2, 533Mhz FSB, Intel 915GM )
512/1024 MB RAM, 40 GB Hard Drive, 15.4 WideXGA XBRITE, DVD±RW Double Layer. "
In fact, the 80 GB Hard Drive is right on my order but i wonder how it is like that? May the manufacturer was w rong when printing the label or the seller lie me? It this possible if the seller replace a 40GB Hard Drive by 80GB Hard Drive? Which is true?
Pls helppppppppppppp me!!!!!!!!!!!!!!!! Thx alot!
