system board (00A) system board CT number error message at start up how to input number which I have

HP Recommended
HP Notebook

Hi. I have the following error at startup:-


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

System Board (00A) - System Board CT Number


As per other posts the battery doesn't charge when the laptop is on and therefore just drains.  It does charge sometimes when the laptop is powered off. Performance is also slow.


I can see others have posted with the same error but cannot find a resolution.  I have the board number now so how do I input it?


Appreciate any suggestions.

Thanks in advance. Paul
