Does your laptop still through that USB-C port? Share public link
If you have recently looked at your Windows Device Manager and noticed a warning symbol on a device labeled ACPI\PNP0CA0 or , you are not alone. This is a common issue, particularly on modern laptops and desktop computers utilizing USB Type-C technology.
Managing this complexity requires a sophisticated controller on the motherboard. In many laptop designs, the BIOS uses the standard to allow the operating system to talk to the USB-C controller. pnp0ca0
For the operating system to safely pass data to the motherboard's power subsystems, your chipset drivers must be fully functional. Install the latest or AMD Chipset Drivers , along with Intel Management Engine Components if applicable to your processor architecture. 📋 Technical Blueprint Summary Hardware ID ACPI\PNP0CA0 or ACPI\USBC000 Device Name UCM-UCSI ACPI Device / UCSI USB Connector Manager Primary System File UcmUcsiCx.sys (Microsoft Core Class Extension) Subsystem Category Universal Serial Bus / ACPI Infrastructure Core Functions
