System board 00a

Microsoft Windows 10 (64-bit)
On startup I get the following message:


'The followng product information programmed into system board is missing or invalid-
System board (00A) System Board CT Number"


I have tried to retrieve the CT number by hitting 'Esc' on startup, then F1. It gives me a product number, serial number, Build ID etc but for 'CT Number' it simply says 'CT Number : HP'


And the laptop is not in warranty

Please help
