Dell Laptop Xps 15 L502x — Display Problem

Address:

Chennai, Tamil Nadu

Dear Sir,
This is Karthick Srinivasan from Chennai. Last month 25 Oct 2011 I've purchased a DELL XPS 15 L502X modeled laptop from a Direct Dell showroom (Bharathi Computers, Annanagar). i used that computer only 3 Hrs, from the date of purchase.
When (15Nov2011) I'm using that laptop suddenly the Display getting off. After that i Complaint this issue to the dealer. They checked and told me "your Display had some problem and we can't correct it". They are not interested to here my words they need only money not Customer Satisfaction (Because of i paid full amount by cash when it was delivery). Same thing the battery backup withstands only 15-17 hrs while not in use the computer. The laptop worth is Rs.80,000 but the Display life is only 20 days...? what a poor design...? i feel "I'm purchasing a second hand laptop........??? not a new one.....!!! "

I'm not satisfied with this computer. I've one year warranty period. Can i replace this entire laptop? What is the procedure for replacement?
