Ignore the previous post.
Nvidia doesn't do 'integrated' graphics for notebooks.
[/url]
Well , no offence but haven't you read/heard about the Nvidia Ion Technology. for Netbooks/Notebooks ?
If no , then please look at "Nvidia's integrated GeForce 9400M graphics" based on Nvidia Ion Technology.
@OP: Ingore all previous posts. All posts above consist of wrong info.
A. There are two type of graphics (card). 1> Onboard- shares memory from RAM. Your display card is of this type.
2> Discrete- Have its own memory. These are PCI or PCI-E cards.
End of story.
But isn't it that the term Discrete GPU is used for Notebooks having Dedicated graphics card with its Own memory & resources, and some of these even share system memory too.
Now there are newer generation processor also called APU , which have GPU on same die as processor.
Therefore no PCIe BUs involved in data transfer from GPU-CPU. These are called Discrete class GPU , for example AMD HD3000 , HD 6320,etc.
They don't have dedicated Ram like Discrete GPUs. However since it doesn't involves delay in data transfer , its much faster than previous IGPs.
These "Discrete class" gfx delivers better performance than some of lower range Discrete GPUs , and more battery life.
AMD and Intel HAs coined their new range of GPUs that comes bundled with APU's as "Discrete class".
This new range of GPU coined by AMD might sound highly different and superior but "Discrete class" is still an IGP and lacks Dedicated memory unlike Original Discrete Graphics.
Don't confuse yourself with "Discrete class" and "Discrete" while going for lower middle range notebooks.
This is what I see in my dxdiag tool.

So it's an onboard graphics, i.e. without any dedicated GPU.
@Rishi: So you mean the discreet class graphics have their dedicated memory and cpu although its parallel with the mainboard CPU.
I wondered about this since I couldn't understand how (for example) intel boards come integerated with ATi and nVidia cards. Do they tie up and built the board accordingly?
PS: In system properties, it shows my usable RAM is only 3GB though I have 4. So my graphics uses 1GB. However, it shows approx 1.5GB in dxdiag. Does that specify how maximum it can share from RAM?
Enjoy~!
1.No ,Discrete class GPU doesn't have dedicated VRAM , they are just advanced IGP delivering performance times better than predecesors and shares system memory.
Check out AMD's FUSION for further details.
2.Recently made Nvidia Ion based GPU's that are actually integrated graphic processors that comes bundled with Intel Atom CPU.
Other than this Nvidia doesn't doesnt have any integrated graphic solution for Notebooks/Netbooks.
3.Your laptop features a Quadro line of GPU , which is actually a Discrete/Dedicated GPU having 512mb Of dedicated DDR3 VRAM.
Its actually a buisness class GPU meant for presentations and multiple displays , and not gaming.
