Disabling Intel AMT (active management technology) in the BIOS creates inconsistent POST

[cmiguel]

Hello,

I have disabled the Intel AMT feature in my notebook BIOS. After that the POST process takes a long time, the logo from HP will take a bit to show up on the screen and while it doesn't the num lock and caps lock leds will blink. Sometimes the fan will start spinning at a high speed, too. If I re-enable AMT feature the laptop posts normally.

I have updated to the latest BIOS version, 

HP Notebook System BIOS Update (N75) 01.33 Rev.A Aug 17, 2018

I have also update the Intel ME firmware to the latest version,

11.8.55.3510 Rev.A Aug 17, 2018

I would like to disable the Intel remote managment without the inconvenient of my laptop taking a long time to post

Here is a video of that happens: https://drive.google.com/open?id=1E2dunDAHBxLOrIBpT0lRe7Kl8c3QpvXU

Could you check what's the BIOS version that your machine is using?
