is a special, Microsoft-defined ACPI Hardware ID. Its official meaning is:
If you see this ID in your system logs or Device Manager, here is what it means for your performance:
On the , this ID usually links to embedded AMD platform management sub-devices (like the AMD AS4 Device or AMD ASD ). On Chromebooks , it typically points to internal audio controllers (like the Google Audio SPI Device ) or custom touch controllers.

A user on a Chromebook forum encountered three devices with hardware IDs ACPI\PRP0001\4&df81603&0 , ACPI\PRP0001\0 , and ACPI\PRP0001\1 . Windows Device Manager showed no driver available for any of them.
Identify the specific hardware (e.g., Bosch Accelerometer, I2C Controller). Its official meaning is: If you see this
Lin felt a cold hand on her shoulder. She looked. Nothing. But the temperature in the room had dropped ten degrees.
Instead, she made a decision.
Next time you see that message in your boot logs, you’ll know:
Device (TDA0) Name (_HID, "TDA7802") // Official vendor ID Name (_CID, "PRP0001") // Allows fallback to DT matching Name (_DSD, Package() ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), Package () Package (2) "compatible", "st,tda7802" ,
When the Linux kernel finds _HID , "PRP0001", it parses the _DSD object to find the "compatible" property. In this example, it will look for a driver that supports vendor,sensor-name . Key Benefits of PRP0001
