Return to Default (Un-Provisioning) Return to default is also known as un-provisioning. An Intel AMT setup and configured computer can be un-provisioned using the Intel AMT Configuration screen and the Un-Provision option. Follow the steps below to un-provision a computer: 1. Select Un-Provision and then select Full Un-provision. Full un-provisioning is available for SMB Mode provisioned computers. This option returns all Intel AMT configuration settings to factory defaults and does NOT reset ME configuration settings or passwords. Full and partial un-provisioning is available for Enterprise Mode provisioned computers. Partial unprovisioning returns all Intel AMT configuration settings to factory defaults with the exception of the PID and PPS. Partial un-provisioning does NOT reset ME configuration settings or passwords. An un-provisioning message displays after about 1 minute. After un-provisioning completes, control is passed back to the Intel AMT Configuration screen. Provisioning Server, Set PID and PPS, and Set PRTC options are available again because the computer is set to the default Enterprise Mode. 2. Select Return to previous menu. 3. Select Exit and then press . The computer restarts. Full Return to Factory Defaults All Intel AMT settings can be returned to factory default by clearing the CMOS (via the jumper or CMOS battery). This includes resetting the password to the default password of admin. However, settings in the ME, such as the ME Power Settings, are not reset. These settings must be manually reset to for the computer to be in a true factory-default state. The table below lists the default MEBx settings. The client cannot be remotely managed until it is set up and configured again.
