Lenovo M5 or X6 systems running Microsoft Windows Server 2016 can be rendered inoperable after applying the Cumulative update for Microsoft Windows Server 2016: November 8, 2016; KB3200970: https://support.microsoft.com/kb/3200970
The system will not complete POST and hangs at the Lenovo splash screen.
Lenovo Workaround until issue is identified: Disable automatic Windows updates. Do not install the Microsoft Windows 2016 Server November update. A future notification will provide further instructions.
On some Lenovo Servers, installing this update will cause the server to fail to start. Lenovo is aware of the issue and is investigating it. For more information, see https://support.lenovo.com/us/en/solutions/ht502912
