Check The description, it's a direct pull from Newegg.com . The laptop seems to be imported so check with the seller first. Warranty is available only if bought from authorised dealers, go to lenovo's website and check if he is authorised regional dealer form chennai. Ask for his shop/company name. I frequently buy from newegg.com, eBay.com(not .in), and Amazon.com (not .in) so i know what you should check before buying .
Frequently i have warranty claim problems due to import status but a good shake up at their head office results in warranty here too
