I am using a Lenovo ThinkPad T420 and Windows 7 prof. x64 as my main workstation. Yesterday I did a reinstallation of Windows 7 (ISO image from MSDNAA and not the Lenovo DVD). After the OS and all drivers (using Lenovo System Update) were installed, I had a look at the device manager and recognized the "Intel management engine interface". Since I don't need this function I researched how this device can be disabled. First I had a look in the System BIOS which stated that AMT is disabled:
So I went back to Windows and had a look in the device manger. The device was still there. I decided to use the "Management and Security Status" Tool which stated, that AMT is active ("Aktiviert" in german):
...but that the connections are disconnected ("Verbindung getrennt"):
I did some further googling which led me to the conclusion, that I have to use the "Management Enging BIOS Extension" (MEBx) to disable AMT. I went back to BIOS, reenabled AMT (otherwise you can't enter MEBx), pressed Ctrl+P on restart and used MEBx to disable AMT:
After exiting MEBx and restarting Windows 7 "Management and Security Status" said, that AMT is disabled ("Deaktiviert"):
...and also the details looked different ("Informationen nicht verfügbar" -> information not available)
I thought that I've finally got rid of AMT, restarted the ThinkPad, entered BIOS and set "Intel AMT Control" back to "disabled". While restarting, the BIOS prompted "Intel ME unconfiguration in progress..."
BUT then this flashed up and stated that AMT is "enabled" (I had to take a movie, sorry for bad quality):
And when Windows 7 was started this happend...
...also the "Management and Security Status" states, that AMT is ACTIVATED
So my question is:
Is it necessary that the BIOS Option "Intel AMT Control" stays "Enabled" to get rid of AMT? Sound strange to me!
Thanks a lot,
