/sys/devices/platform/acer-wmi/rfkill/rfkill4/ ← WiFi
/sys/devices/platform/acer-wmi/rfkill/rfkill5/ ← Bluetooth
```

Request

Could you check which WMI GUID handles the Turbo button on this model?
RGB working confirms the module loads correctly on PHN14-51, so turbo
support may just need the correct GUID mapping added.

Happy to test any patches or provide additional debug output.
