I hate to dig up an old thread but this is highly relevant.
I won the case against HP. You can view a scanned copy of the consumer court judgment at my website (DOC format). Basically HP owes me Rs.96,000 in cash or kind and the order is supposed to be executed by the first week of December.

I hope this encourages those of you who are in similar situations to exercise your rights as a consumer.
