Hello! So the rule of thumb is, if you buy direct from Dell you get the Dell warranty which starts after invoicing (shipping) to your location. If you buy from Amazon, eBay, etc., you don't know if the computer is new, used, or how long its been sitting and Dell may only honor partial warranty or nothing at all especially if they are not a Dell Authorized Re-seller. When you receive the unit, you will have to do a warranty transfer which can be found here. This will transfer the warranty from the US to India.
Thanks for reaching out. Yes, you will have to purchase the laptop with Premium/prosupport warranty to avail international warranty service. However, in case if it leads to part replacement in future, Dell India will be able to source the parts only if the model and the configuration if available in India. We recommend you to purchase the laptop via Dell as the premium/prosupport warranty services is available only with Dell and not with any retailers.
Thank you for your message.
Please click on this link http://dell.to/2hHlC4d to complete the ownership transfer online. Once completed this process may take about 10-15 days to complete.
However, the service depends on the availability of that product in your region & the system should have an in-home service to get an international warranty.
