On bootup... (A7) Me Fw Downgrade - Request MeSpiLock Failed

The problem seemed to come out of nowhere a couple of weeks ago.  Error causes lengthy boot.  I've tried all the tests of the hardware etc., and updated the BIOS to ver 2.53.  I have removed the onboard battery with power off then re-assembled and re-booted, tried some BIOS setting changes all to no avail.  In other words I'm now fresh out of ideas.  I'd rather not have to load Win 10 (the Pro version) if I don't have to, but that's my next step unless someone can help me.  (I don't even know if re-loading Win would get rid of the error.)

Many thanks
