Acpi Nsc6001
Windows 10/11 does not have built-in drivers for 2000-era infrared ports.
Since infrared technology is obsolete, having an un-configured device in your Device Manager uses system resources for no reason. Disabling it is the cleanest, safest, and most practical approach. Open the .
Use the arrow keys to navigate to the or Peripheral Configuration menu. Look for entries labeled Infrared Port , Fast IR , or IrDA . Change the setting status to Disabled .
If you are reviewing this because of a missing driver (the "Unknown Device" error), you can often resolve it without downloading third-party software: Open .
Look for and select the National Semiconductor (NSC) or generic IrDA driver provided by Microsoft. acpi nsc6001
The device is handled by the nsc_gpio , nsc_ircc (IrDA), or geode-wdt kernel modules. Check if loaded:
stands for Advanced Configuration and Power Interface. It is the part of your operating system that manages power consumption and hardware configuration. NSC6001 is a hardware ID representing a Fast Infrared (FIR) transceiver chipset manufactured by National Semiconductor.
Some embedded systems, industrial PCs, and thin clients (e.g., Advantech, IEI) still include legacy Super I/O chips for serial/parallel port compatibility. Also, certain ASRock and Gigabyte boards have a BIOS option called "ACPI Auto Configuration" that sometimes generates ghost devices.
Choose "Let me pick from a list of available drivers on my computer". Windows 10/11 does not have built-in drivers for
Zero resource consumption; zero risk of malware; permanent fix. The port cannot be used if needed. 99% of modern users. Digitally signed by Microsoft; highly stable; no bloatware. Requires manual manual extraction of .cab files. System purists and IT professionals. Legacy OEM Packages Includes automated installation wizards.
The system may take 2-3 minutes to shut down because Windows waits for the NSC6001 device to report a successful power transition. Eventually, it times out.
If you have recently opened your Device Manager on an older Windows laptop or desktop, you might have been greeted by a glaring yellow exclamation mark. Among the cryptic hardware IDs causing driver headaches is ACPI\NSC6001 (*NSC6001).
National Semiconductor sold the Geode line to AMD. If you are running an older OS: Open the
When reinstalling operating systems like Windows 7, 8, 10, or 11, this hardware frequently appears in Windows Device Manager marked with a yellow exclamation point as an "Unknown Device". While infrared data transfers are mostly obsolete today, clearing this error is essential for complete system stability, optimized power management, and clean Device Manager logs. 🔍 What is the ACPI\NSC6001 Device?
The hardware ID points directly to a legacy National Semiconductor IrDA Fast Infrared Port . Typically found in mid-2000s laptops like the Acer Extensa 5220 and 5620 series, this device frequently shows up as an "Unknown Device" in Windows Device Manager after a clean operating system installation.
If the native update fails, legacy support packages hosted on repository sites contain the original installation files:
