Thank you for posting on the HP Support Community.

• Did you make any software or hardware changes on your PC?
• Did you replace the system board on your PC?

Please try the steps recommended below:

You might see this message after the system board is replaced. The message indicates that the serial number was not entered, or was entered incorrectly, after replacing the system board or other components.

To resolve this issue, contact HP using the Contact Support tab at the top of this screen. You will be asked to provide the fourteen-digit System Board Commodity Tracking (CT) Number. Use the steps in one of the following sections to find the CT Number:

• Find the CT number in system information.
• Turn off the computer.
• Turn on the computer and immediately press the Esc key repeatedly, about once every second.
• Press F1 to view System Information.
• Find the System Board CT Number listed on the System Information screen.

Thank you for posting back. 

I did go through your computer product information and found out there is no HP notebook BIOS DMI tool for public download and use.

You will need to have an HP technician "tattoo" your BIOS with the product model number and serial number.

I would request you to contact our Support and our Support Engineers should be able to sort this out. HP Support can be reached by clicking on the following link: www.hp.com/contacthp/
