What is the ACPI x64-based PC Windows Driver?
The ACPI x64-based PC driver refers to the support for an ACPI-compliant system in a 64-bit Windows environment. ACPI stands for Advanced Configuration and Power Interface, which is an open standard that provides an interface between the operating system and the hardware to manage power consumption, device configuration, and system events.
When you see ACPI x64-based PC in Device Manager under "System Devices," it generally refers to the system's ACPI BIOS and related power management components, not a specific hardware device like a graphics card or network adapter. The "x64" part refers to the fact that your system is using a 64-bit version of Windows.
