The identifier ACPI VEN-MSFT AMP-DEV-0101 refers to a specific defined in a computer’s ACPI (Advanced Configuration and Power Interface) tables. It is not a physical piece of hardware but rather a software-defined device used by Windows.
The sensor responded. The light reading jumped to a value that made no physical sense: 0xFFFFFFFF . Saturation. Overflow. And then, in the raw data register, a string of hex appeared:
This is the most revealing part. Historically, “AMP” in this context refers to , but in modern Windows 10 and 11 builds, it specifically relates to the Windows Audio and Power Management Proxy Device . The ID DEV-0101 is a unique identifier for a Microsoft-provided interface that helps manage audio streams during low-power states (like Modern Standby / S0 Low Power Idle).
Here is a comprehensive guide to understanding what this error means and exactly how to fix it. What is ACPI\VEN_MSFT&DEV_0101? acpi ven-msft amp-dev-0101

The cause of the missing driver varies depending on your version of Windows:
The ACPI VEN-MSFT AMP-DEV-0101 is used to identify and manage an audio device on a computer system. This device is likely an audio amplifier or a sound card that provides audio output. The identifier ACPI VEN-MSFT AMP-DEV-0101 refers to a
The ACPI VEN-MSFT AMP-DEV-0101 is a device identified under the Advanced Configuration and Power Interface (ACPI) standard, associated with Microsoft Corporation. This document outlines a proposed feature for the integration and management of this device within operating systems.
Without the VMBus connection active, the guest operating system relies on slow, emulated legacy hardware rather than optimized synthetic hardware channels. This leads to high CPU utilization, sluggish mouse tracking, limited display resolutions, and an inability to share clipboard data or files smoothly between the host machine and the virtual machine.
If that fails, visit your manufacturer’s support site (e.g., HP Support, Dell Support, or Lenovo Support) and download the latest or Intel Management Engine drivers. The light reading jumped to a value that
Specifically, VEN-MSFT AMP-DEV-0101 is used by the to:
