FNBT0000 is a symptom of lazy firmware engineering. Instead of using standard ACPI methods like _HID (Hardware ID) with a registered PnP ID (e.g., PNP0C32 for a wireless control button), the OEM invented a custom ID. They then wrote a kludge driver for Windows, but never submitted it to Microsoft's Update Catalog. For Linux users, this is a non-issue—the acpi_osi kernel parameter or a simple acpi_listen script can bind the event. But on Windows 10? You're left with a permanent yellow flag unless you dig up a 2015-era OEM driver.
The driver identified as is a specific hardware ID typically associated with the Airplane Mode HID Mini-driver or Virtual Keyboard driver . It is most commonly found on devices like the Intel-powered Classmate PC and some Noblex or Lenovo laptops. Review & Functionality
The following steps outline the standard procedure for resolving the missing driver issue.
That is not a typo. *NUL . The asterisk is forbidden in official ACPI identifiers.
Most of the time, the yellow mark disappears after you:
