@gozza1 Welcome to HP Community!
To find the CT number printed on the system board on your notebook computer, open the memory access door or service door & if this isn't available anymore as you've mentioned, the CT number is often located near or under the primary SODIMM memory slot.
For instructions to complete this procedure, refer to the Maintenance and Service Guide for your notebook model,
found in the User Guides section of your product page on the HP Customer Support website.
To resolve this issue, contact HP using the Contact Support tab at the top of this screen. You will be asked to provide the fourteen-digit System Board Commodity Tracking (CT) Number.
If none of the above works, you may need to discuss your repair options with HP as the OS re-installation/recovery cannot fix this issue:
follow the below steps to get started:
1) Click on this link - http://www.hp.com/contacthp/
2) Click on Sign-in or select the product using the below step:
3) Enter the serial of your device.
4) Select the country from the drop-down.
5) Click on "Show Options".
Fill the web-form, to populate a case number and phone number for yourself!
Also, if you are having trouble navigating through the above options, it's most likely because the device is out of warranty, if yes? please send me a private message with the region you are contacting us from,
