Your Specs show an Intel Exteme Grafix chip.
Unfortunately this form of grafix acceleration is hard-soldered into your laptop's motherboard and upgrading will not be possible.
Manufacturers are going back to onboard grafix chips with shared memory architechture because they do not want the user to be able to upgrade components, much more money to be made from a punter who gets annoyed with his laptop's lackluster performance 12 to 24 months down the road and just springs for a whole new one.
I always buy laptops that are fully upgradeable.
Desktop systems use an AGP or Accelerated Graphics Port, a dedicated slot providing more bandwidth for data transfer than the old standard PCI slots, these come in speeds of 2x, 4x and the newer 8xAGP. ( soon to be replaced by PCI-Express )
Laptops may also come with a micro-AGP slot, the later ones are all 8xAGP and will allow you to upgrade your grafix card at will.
I would recomend PROSTAR laptops.

I always buy from these guys and get the best bang for the buck, my latest laptop specs are listed below:
15.4 Inch 1050 x 1400 pixel display
Intel P4 3.2 Ghz CPU on 800Mhz front Side Bus ( 1066 mhz poss )
1 gig of DDR400 memory ( 2 sticks )
60 gig hi-speed 7200 rpm hardrive
wireless and bluetooth
Highspeed ethernet + dial up
dvd/cdrw combo drive
24 bit 5.1 surround sound
and....8X AGP ATI radeon Mobility 9700 128 meg dedicated video
All the above components are upgradeable within reason, the motherboard will recognise any socket 478 Intel CPU.
And the grafix are whatever you want to buy: nvidia or ati that will fit under the keyboard and uses the micro AGP interface.
Ram may be upgraded to 2 GIG
Hardrive may be upgraded to whatever you want
DVD/CDRW drive may be upgraded to a DVD burner
I paid $1750 for the above laptop, a little on the high side but about $500 or more less than known namebrand laptops.
Any questions like if you want me to send you one marked as ' warranty return electronics ' LOL, then drop me an email .
Cheers Marc.
