ACPI Driver Installer 2.1

ACPI Driver Installer by Intel Corporation

ACPI Driver Installer is a utility that installs and updates the Advanced Configuration and Power Interface (ACPI) drivers required for Intel-based systems. It ensures the operating system correctly identifies platform devices exposed through ACPI and manages critical functions such as power states, battery reporting, thermal controls, and wake behavior. By providing platform-appropriate ACPI components, the installer helps resolve “Unknown device” entries in Device Manager, improves power efficiency, and enhances overall system stability—especially after a clean OS installation or major driver update.

Key benefits:

• Automatically detects supported Intel platforms and installs the matching ACPI components
• Enables reliable sleep/hibernate, lid and wake events, and accurate battery and thermal telemetry
• Reduces configuration time with a guided, minimal‑input setup process
• Suitable for OEM images, IT deployments, and end users refreshing drivers on Intel‑based laptops and desktops

Notes:

• Compatibility and feature support vary by system model and operating system version
• Administrator privileges are required; a system restart may be needed to complete installation
• For best results, review your system manufacturer’s guidance and the release notes to confirm compatibility
