dear sir,
i bought a dell s2240l monitor from a retailer popular computers, vellore with a bill. when i tried to register the monitor for warranty purpose the service tag number required. but i could not find any service tag no. in the monitor. i found only the s/n cn-01mvd1-64180-473-0zzt only. but with this i could not proceed for the warranty registration. i found two other two numbers 8 84336091615 8 and dp/n 01mvd1 in the box. kindly advise me the way to get my monitor registered for warranty. i bought it on 02.12.2014.
