I followed the directions and went to the suggested website, followed those directions to find the product information and the System Board CT number is missing - how do I find it and how do I correct this problem so that I can use my computer with a normal startup when I turn it on.

Hi! @jmt3, Thank you for visiting the HP Forums! A great place where you can find solutions for your issues, with help from the community!
I understand you are getting system board CT number is missing or not valid error on your PC.
Don't worry I'll try to help you out.
Did you make any software or hardware changes on your PC?
Did you replace any hardware on your PC previously?
If the system board was replaced on your PC. The product information stored in the BIOS chip would have got erased.
You have to contact HP and get the PC serviced.
HP uses a tool called DMI tool by which the product details are entered on your PC.
However, this tool is limited only to HP partners and HP service center technicians.
I will share you few details through a private message about the service options for your laptop.
Please watch your inbox for more information.
Hope this answers your query!
Have a pleasant day ahead! 🙂
