This started the same day that I upgraded to Bios F.29 and I can not figure out a way to rollback the BIOS to test if that was the cause

I'm ten days past the extended 3yr care package, tough luck ... but maybe this is worth a shot,

Thanks already!

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, 

After reading your post, I did go through the failure ID and it refers to the USB Port Failure 434. This is hardware related issue with the USB port and in order to fix this issue,  your computer needs to be serviced.  As we have limited support boundaries in the support community as of now. 

I would request you to reach out to our Support and our Support Engineers should be able to check the available service options in order to diagnose the computer physically.  HP Support can be reached by clicking on the following link:  www.hp.com/contacthp/
