[Resolved]  Dell Xps 1550 Laptop — faulty motherboard

Hi All,
I have been using DELL XPS 15inch laptop for over a period of 15months. I had a complain about heating up my laptop and DELL replaced the Motherboard, Heat sink in warranty period.
And exactly after 93rd days of the replacement my motherboard died again.
I contacted DELL, they are saying any replacement part has a warranty period of 90 days.And saying it is very unfortunate of me to having a fault detected after 93rd day.
Now I have to pay Rs.14000/- to have another motherboard.

I would like to know if I could have DELL pay some attention to my problem.
