Dell — Issue with the price

Address:

Ernakulam, Kerala

Sir,
I purchased a laptop Dell M501R from a retailer in Ernakulam district of Kerala for Rs.38000(including some items that were called 'free') a month ago.(In the bill they had added the free items also with some price). I was offered many features while buying but after a week o[censored]se I realized that many promises made were false.One of those is the battery life of the laptop which was supposed to be 3 hrs,but it hardly gives 1.5 hrs now(this is really affecting my usage).On top of all these, to my disappointment I learned that the laptop was actually priced low @ Rs.32000(a difference of Rs.6000!!!) in some other shops that I came to know online and from inquiry.(In fact,its priced at Rs.30500 in flipkart.com which I am not considering now as you have to take into account taxes etc. for retailers-link( http://www.flipkart.com/computers/laptops/dell/itmd37zvcdyb4kqw?pid=comd37zufyzxzb74&_l=+VWuyNB...⇄ all these, when I checked the Dell website for the actual price of this laptop,I was shocked to learn that Dell had stopped the production of this model some months ago and this model does not feature in their website(http://www.dell.com/in/p/inspiron-m501r/pd).
Things that I could conclude from all these is that the retailer is selling the old stock of this production stopped laptop at his own price. Since the consumer has no official sources(Dell website) to know the actual price of this laptop they were successful to some extent in cheating the consumer. When I enquired to know whether this retailer usually sell laptops at higher rates, I realised that it was not the case. It was only with that particular model, he’s doing so which again points to the foul play that I mentioned earlier. The fact that the laptop was priced way too high for me and that it doesnot have all features promised earlier, has really depressed me.
I admit that I was ignorant and should have been more vigilant while making the purchase.But I feel badly cheated and would like to claim a compenstion from the retailer.Please guide me in this regard.
