I wanted to let you know about the Warranty Status Check website that HP has. In order to look up the status, you'll need to enter your serial number and model number.
The Serial Number (s/n) is a ten-digit alpha-numeric number that is unique to your product.
The Product Number (p/n) is a six or seven-digit alpha-numeric number that identifies your product. If there is a pound sign (#) or a dash (-) in the p/n, enter only the letters and numbers before the # or - sign.
Both numbers can be found on the Universal Product Code (UPC) or Service Tag sticker located on the back, side, or bottom of your product.
