HP 15-ac121dx Boot Error Missing or invalid "System Board (00A) - System Board CT Number"

[SysEngineer305]

Hello HP Community.

I had an HP 15-ac121dx that all of a sudden reported the following error upon boot.

Product Information not valid.

The following product information programmed into the system board is missing or invalid.

System Board (00A) — System Board CT Number

ENTER — Continue Startup

For more information, please visit: www.hp.com/go/techcenter/startup

The system boots and operates fine after I hit enter. But id like to get this resolved.

My research points me to some special HP DMI tools. I as a consumer, I don't have access to, nor had much success finding the correct version and files to correct this.

In the meantime, while I wait for a solution, I can do it myself. I did run into this page.

System Board (00A) Product Information Not Valid Error

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

Contact HP to service the computer. The procedure must be performed at an HP authorized service center.

Go to HP PCs - System Board (00A) Error Appears on a Black Screen for further assistance.

However, when visiting the HP PCs - System Board (00A) Error Appears on a Black Screen  link, I am taken to a 404 page
