Invalid Serial Number error displays before computer starts
This document pertains to HP PCs with Unified Extensible Firmware Interface (UEFI) beginning in late 2008.
On startup, a warning message displays, indicating that the system has found an invalid serial number:
Product Information not valid
The following product information programmed into the system board is missing or invalid.
System Board (00A) - X XXXX XX XX XX XXX
You might see this message after you send your computer in for service. It indicates that a technician replaced the system board or component but failed to input the new serial number in the system.
To resolve this issue, contact HP for further assistance. You will be asked to provide the fourteen-digit System Board Commodity Tracking Number (CT) that is included in the error message.
