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'
Is this an error that will effect my laptop's performance?
If not, what is suddenly causing my laptop to work ridiculously slowly? Have run all firewall scans, defragged, downloaded appropriate updates to software, what more can I do to improve speed/performance please?
Solved! Go to Solution.

I have brought your issue to the attention of an appropriate team within HP. They will likely request information from you in order to look up your case details or product serial number. Please look for a private message from an identified HP contact. Additionally, keep in mind not to publicly post personal information (serial numbers and case details).

That is unknown because the original author of an issue forgot to come back to his thread and tell us how it went.
This is something that happens fairly frequently.
Has your issue been resolved?
Is your notebook still in warranty?
Did you contact the Support staff directly to resolve this under warranty?
