  4. Force reinstall — uninstall the device in Device Manager and scan for hardware changes.

The PNP0CA0 identifier is typically used in conjunction with other ACPI device IDs, such as PNP0C0A, PNP0C0B, and PNP0C0D, to identify specific ACPI devices, such as battery controllers, thermal zones, and power management units. These device IDs are used by the operating system to configure and interact with the corresponding ACPI devices. pnp0ca0
