I was working with AMT that I configured in Admin mode, and everything was fine. I work on a Dell Latitude on Windows 8.
Today, the tab "AMT" is not in the Intel Management and Security Status anymore. The Intel Management Engine status is now "Information unavailable".
Also, when my computer boots, I have an error message before Windows starts : "(A7) Me FW Downgrade - Request MeSpiLock Failed". I tried to reconfigure AMT in the BIOS, but the line Intel Management Engine is not here anymore.
Does anyone understand what happened ? Do you have any ideas of how I can have the AMT back ?
Thanks in advance
