Invalid S/N, can not detect machine type

I have tried updating my laptop through the Lenovo website, but couldn't detect my hardware. Discovered my S/N and Machine type is listed as INVALID. Went into my settings and about my hardware and it said the same thing. Recently reset my computer ,but it didn't fix the problem, still can't detect machine type and S/N. 

My motherboard was replaced about 9 months ago.


Anyone know why/what to do?

The type and serial number are normally set using service tools when a board is replaced. Authorized service providers should have access
