Acpi Nsc6001

Feature Name: IntelliTherm

Description: Building on the ACPI framework and utilizing the NSC6001 component, the IntelliTherm feature aims to significantly enhance the thermal management and power optimization capabilities of computing systems. This feature would enable more intelligent and dynamic control over system temperatures and power consumption, ensuring optimal performance while maintaining efficiency and prolonging hardware lifespan.

The ACPI NSC6001 error is not a hardware failure. It is a software configuration problem rooted in Windows' Plug and Play driver database.

If you are reading this article, you likely see ACPI NSC6001 in Device Manager with an error code. Common codes include:

You have three options depending on your needs: Hide it, Force it, or Disable it.

Microsoft sometimes pushes legacy drivers via Windows Update. acpi nsc6001

If you’ve recently dug into the Windows Event Viewer, checked Device Manager, or troubleshooted a Blue Screen of Death (BSOD), you may have encountered a cryptic entry: "ACPI NSC6001."

For most users, this string of letters and numbers means nothing. For IT professionals and advanced hobbyists, it signals a specific hardware driver conflict related to legacy National Semiconductor chipsets. In this 2,500+ word guide, we will dissect what ACPI NSC6001 is, why it appears, what errors it causes (including BSODs like DRIVER_POWER_STATE_FAILURE), and step-by-step methods to resolve it permanently.

The presence of this device isn't always harmful, but when it misbehaves, it triggers several distinct problems:

The hardware identifier ACPI\NSC6001 (often seen as ) refers to the National Semiconductor IrDA Fast Infrared Port

. If you see this listed as an "Unknown Device" in your Windows Device Manager, it means your computer has an infrared sensor that lacks the necessary driver to communicate with the operating system. Identification and Function Feature Name: IntelliTherm Description: Building on the ACPI

The "ACPI" prefix indicates that the device is managed via the Advanced Configuration and Power Interface

, which handles power management and device discovery between your hardware's BIOS and Windows. The "NSC" tag identifies the manufacturer as National Semiconductor Microsoft Learn

Specifically, this ID belongs to infrared communication chips like the

series. In the early-to-mid 2000s, these ports were common on laptops for: Wireless Data Transfer : Sending files between laptops or early PDAs. Peripheral Connection : Connecting to infrared-enabled printers or keyboards. Why It Appears as "Unknown"

This device is most frequently found on legacy or budget-friendly laptops from the mid-to-late 2000s, such as the Acer Extensa 4620 , 5220, or 5620 series. It is a software configuration problem rooted in

When users upgrade these machines to newer operating systems like Windows 7, 8, or 10, the system often fails to automatically identify the infrared port because modern hardware has largely replaced infrared with Bluetooth and Wi-Fi. How to Resolve the Issue

If you need to clear the "Unknown Device" error in your Device Manager, you have two primary options: Install the Driver

: You can find the driver by searching for the "National Semiconductor IrDA" driver on the Microsoft Update Catalog Acer Support Page for your specific laptop model. Disable the Device

: Since infrared technology is rarely used today, most users simply right-click the "Unknown Device" in Device Manager and select
