Troubleshooting Unknown Devices
If you encounter an unknown ACPIMSFT0101 device in Device Manager, it could indicate the need for an ACPI driver. HP has released an official driver for Windows, available on the HP Support website. In addition to the ACPI driver, HP has provided various other updates for Windows, such as drivers for video and chipset components.
For specific issues related to AMD HDMI audio or TPM in Windows 7, ensure that you have the latest AMD graphics drivers installed. If you're experiencing TPM issues in Windows 7 32-bit, there is currently no official driver available. However, switching to Windows 7 64-bit will allow you to install the necessary ACPI driver.
To clear your TPM, navigate to Start > Settings > Update & Security & Windows Security & Device security. Select your specific Intel NUC model and Windows version, then download and run the ACPI driver installer. Follow the on-screen prompts to complete the process.
If you continue to encounter issues, it's recommended to right-click on the unknown device in Device Manager and select Uninstall, checking the Uninstall driver box. Restart your PC and hope that the issue resolves itself.
Details about the unknown device can be found by expanding Properties in Device Manager. The device name, ACPIMSFT0101, will be displayed under Details > Device instance path. This device corresponds to the TPM module, which is responsible for security-related functions.
For users with a second-hand device, it's essential to be aware that drivers may not be up to date. It's recommended to download and install the latest drivers from the official HP Support website.
