3)Enter the serial number of your device or select let HP detect your product option.
4)Select the country from the drop-down.
5)You should see the HP phone support number or Chat option listed.
In case, if the HP website is showing that the warranty is expired and you have purchased the computer within the last 1 year then contact the store or the online store and request them to issue a duplicate invoice.
In most of the eCommerce website, there will be an option to download the invoice in case if you have purchased it online.
Let me know how it goes and you have a great day!
