Can I put new Graphics Card in my laptop?

Hello… I have a Lenovo laptop…
1. OS- Windows 7(32bit)(60Hz)
2. Processor- Intel(R) Pentium(R) CPU B950 @2.10 GHz, 2 CPU(s), 2 Logical Proce…
3. RAM- 2GB
4. DirectX Version- DirectX 11
5. Graphics Card- Intel(R) HD Graphics Card
6. Hard Disk- 500 GB
7. Adapter RAM- 751 MB
***************************************
My Graphics Card is not enough for playing heavy games (i.e, GTA IV), so I want to buy & add new Video Card (like-Asus NVIDIA GeForce EN210 Silent 1 GB DDR3 Graphics Card) on it… Will my motherboard manage this? Or something more need to do this…

Most of the hardware components inside your laptop are soldered to motherboard during manufacturing process. Hence, it's next to almost impossible task to upgrade them

Only RAM, battery, keyboard, touchpad and screen can be replaced or upgraded

I don't think it is possible as laptop have its fixed slots unless you're doing it on a desktop

from what i know only ram and harddisk is changeable
