HP pavilion dv4 1240 tx
Faulty product

It has been almost 7 months that i have bought this laptop for Rs 47000 and till date i have had 3 major faults in the laptop. my hard drive had failed twice and the display has been changed once. i being an MBA student have lost important subject matter in the two hard drive failures and i am too worried that there will be some other issue with this product in the coming few months. although HP has had my parts replaced but i am very much frustrated with this product, after all it has cost me almost half a lakh rupees. and my warranty will be getting over in the next five months. i need your help in this regard.

thanks in advance
