HP Recommended
Product: HP Notebook - 15-af155sa (ENERGY STAR)

After power on the display reads:-

Product Information not valid

System board missing information

It is missing 

Product name

Product serial number

Product number

System board CT number

all of which is printed on a label inside attached to the motherboard. 

How to update the Bios with this data? 

 

The Win10 laptop now has no means of Internet access. Win10 reports the wireless NIC is working, but it is not. The ethernet connection is not working.

Windows update rolls back after it fails to link to Windows home (probably?). 

I have other working machines.

 

Internal Bios update from boot (Windows key + b) 'worked' but that did not help. 

Any assistance would be greatly appreciated.
