Inspiron N5110: changing from 'Intel HD graphics 3000' to 'Nvidia GForce GT 525M'??
Inspiron N5110 comes with two graphic processors:
-Intel HD graphics 3000
-Nvidia GForce GT 525M
When I check with 'Appearance and Personalization -> Advanced settings' is says the adapter type as the intel HD. I want Nvidia to be used as the default adapter 'coz I don't want Intel HD taking off 1632 MB (shared system memory) of my valuable RAM.
How do I make this possible?

You cannot. The system will always use the Intel chip as its primary video device. The nVidia one is called into action either automatically or by means of the Optimus control panel.
Note: NOT ALL of these systems have nVidia chips - the nVidia hybrid is an option at purchase time.

Windows 7 allocates system RAM for video purposes, regardless of what's controlled by the video chip. No matter what you do, you'll still see that allocation.

Does that mean technically I have only 4GB - 1632MB of RAM to be used by other applications?
What changes will it make if I install the latest drivers from Nvidia?

Does that mean I have only (4GB - 1632MB) usable RAM?

Define "useable". All the RAM is useable - by design, Windows offloads a lot of work to the GPU, so it IS being used - for video purposes.

So the memory shared with the graphics card is usable by other applications if the computer is running out of RAM. right?
btw what will happen if I disable the 'Intel HD' from the device manager, leaving out only the Nvidia?

You cannot disable the Intel video - if you do you'll get no video at all. It's the primary video device in the system.
You're not understanding how Windows 7 operates. The operating system by design allocates tasks (and memory) to the video processor itself:
