Next to impossible!
I'm dead sure no 17"er ATM would come with a C2D processor. C2D is EOL already - replaced by the entry level i3 processor which is by no means hifi FYI.
I'll reiterate again - Dell has no 17"er retailing in India ATM for anything you are going to shell out. HP/Compaq may have them but their customer support is nowhere close to what Dell offers and I've seen their laptops conking off pretty sooner than a Dell or an Acer.
Under 40k, if you can leave the requirement of a 17" screen, you can get a good model with a complete cover support for 3 years.
My friend recently got himself a Inspiron 14R with 3 yr CC for just under 40k.
