X1 Carbon (3460) windows 10 (64bit).
Today ran BIOS update as I have done many times before. But at the end of this after screen saying update successful it doesn't reboot just goes off. After a few mins I power up to be greeted with splash screen then long beep "fan error!" Warning then off. I have tried re-setting but no luck. It seems like extreme coincidence that fan fails immediately after bios update! More likely fan doesn't like new bios (I don't hear it spinning up). How do I go back to old BIOS on a pc pc t won't let me boot up? Thanks
