: unplug the laptop, hold the power button for 15–60 seconds, and restart. This forces the hardware controller to re-handshake with the Windows UCSI driver. BIOS Implementation of UCSI - Intel

However, with the introduction of Windows 7 and later versions, the operating system began to handle PNP0CA0 more efficiently. The driver is now included in the Windows kernel, and it's automatically managed by the operating system.
As computing moves toward disaggregated memory, chiplet architectures, and more granular power gating, the role of container devices like PNP0CA0 will only grow. The ACPI specification continues to evolve (version 6.5 as of 2024), with new PNP IDs being deprecated and replaced by vendor-specific UUIDs (e.g., _HID = ACPI0006 for a processor container). However, PNP0CA0 remains a stubborn artifact of the transitional period between legacy PC/AT hardware and fully declarative, firmware-agnostic power management.
