Like any other device, the VEN-MSFT AMP-DEV-0101 device can experience issues that can affect its performance. Some common issues with this device include:
For more technical details on how Windows handles these objects, you can refer to the Trusted Execution Environment ACPI Profile on .
Often, the hardware identifier fails because the security processor is partially disabled or stuck in a legacy state within your motherboard firmware. Shut down your PC completely.
User reported: ACPI MSFT0101 error after clean-installing Windows over Ubuntu. Solution: The laptop shipped with an Intel AOAC power management interface. Installing the Dell "Intel Chipset Device Software" driver pack resolved it. acpi ven-msft amp-dev-0101
Since this is a Microsoft device, the driver is already on your PC—Windows just isn’t looking in the right place.
In this role, MSFT0101 acts as a low-power co-processor interface for "Always On, Always Connected" (AOAC) functionality. It helps manage network connectivity and sensor activity while the screen is off. On properly configured AOAC systems, a specific driver from the OEM (like Intel Serial IO or Microsoft's own Surface firmware) should bind to this ID.
