Unknown Device - Device Instance Path (ACPI\INT33BD\1)

HP Notebook - 15-r132wm
Microsoft Windows 10 (64-bit)

I have a unknown device in device manager. When I plug in my power cord to charge i get a black screen as soon as i unplug the windows screen comes back. Not sure if these are related or not.

Hi:

 

I am pretty sure you need this driver.  The latest is for W8.1.

 

This package provides the driver that enables the Intel SidebandFabric device. Intel Sideband Fabric Device Driver is a bridge tothe Intel Dynamic Platform and Thermal Framework. This package isprovided for supported notebook models that are running a supported operating system.

 

File name: sp65474.exe

 

I don't know if not having that driver installed is related to the black screen issue.
