This m15 R4 was purchased in the USA with Basic warranty only. The warranty was never transferred to India. Yes, parts can be replaced in India. But a like for like used system exchange can only happen here in the USA.
In month of march i purchased a laptop from dell us and at the time of purchase I transfered my ownership to india now after 2 months of purchased I faced 4-5 different issues in the laptop, after multiple repairs which were a cause of thier unprofessional technicians I opted for a complete replacement but they aren't the dell replacement team is not agreeing with me that my laptop will not be replaced, even the laptop is sold in India and my warranty is completely transfered to india, and now my product has no relation with dell us neither it is registered there.
