Dell laptop warranty extension

Hello! Thank you for reaching out to us. I am your Dell-Cares contact for order related queries. Unfortunately, our customer service is currently unavailable. We are available Monday through Friday. Please reach out to us on any of these days and we will be glad to assist you. Thanks for being a loyal Dell Technologies customer.

You will need to call your local Dell sales number to get that information.  The cost will depend on the system model, what's covered and for how long.
