Hi Thurman L. Lewis,
To check the warranty status of a Microsoft product using its serial number, please visit the official Microsoft Device Service and Repair page. After signing in with the account associated with the product, you can enter the serial number to view warranty details and available support options.
If the product is registered, warranty information will be displayed automatically. For unregistered devices, you may be prompted to complete registration before viewing coverage.
Let us know if you need help navigating the portal or verifying your serial number.
Best regards,
Quinnie Quoc.
