If you don't have the exact driver file, you can let Windows search for it.
To avoid encountering similar issues in the future:
The ACPI ID is a unique code Windows uses to identify hardware components integrated into your motherboard or laptop’s firmware.
This language allows Windows to control the power distribution to various hardware components. It's responsible for critical tasks like putting your computer to sleep, waking it up, managing battery charging, and monitoring system temperatures. The string 2&DABA3FF&0 is a unique identifier assigned by Windows to a specific device on your system. acpi wstadef 2&daba3ff&0
Because WSTADEF is (not a predefined ACPI ID like PNP0C0A for battery or INT33A0 for GPIO), common associations include:
The hardware ID (often seen as part of the ASD0001 or INT3400 series) generally refers to the AMD Sensor Device (ASD) or components related to the Intel Dynamic Platform and Thermal Framework . This device is responsible for managing system power, thermal states, and sensor data to optimize performance and battery life. Device Identification Hardware ID : ACPI\WSTADEF\2&DABA3FF&0 Common Associations :
Here’s a breakdown:
To understand this "digital name tag," we have to look at its three components: ACPI (Advanced Configuration and Power Interface): It's responsible for critical tasks like putting your
Advanced Configuration and Power Interface; handles hardware/software power management.
Here’s a technical write-up covering the string ACPI WSTADEF 2&DABA3FF&0 . This appears to be a hardware identifier from the Windows ACPI (Advanced Configuration and Power Interface) subsystem, often seen in under a device’s “Details” tab → “Hardware Ids” or “Compatible Ids”.

It often represents the HP Wireless Button Driver . This software handles the communication between the physical button (or Fn key combo) and the operating system to turn Wi-Fi and Bluetooth on or off.
