Acpi Nsc6001 -

The ACPI\NSC6001 ID refers to the National Semiconductor (NSC) IrDA Fast Infrared Port. This hardware component was commonly found in laptops from the early-to-mid 2000s, such as the Acer Aspire 1360 series, to facilitate wireless data transfer via infrared light. Technical Specifications

Primary Causes:

| Cause | Explanation | |-------|-------------| | Legacy ACPI tables | Your motherboard's BIOS contains ACPI tables referencing an NSC6001 device, but Windows 10/11 no longer ships with a dedicated driver. | | Incorrect driver migration | Upgrading from Windows XP/Vista/7 to 10/11 carries over an entry for NSC6001 that no longer exists in the new OS. | | Chipset driver residue | Old Intel or VIA chipset drivers sometimes leave behind NSC references even after uninstallation. | | Virtual machine passthrough | Hyper-V or VMware passthrough of legacy PCI devices can erroneously create this ACPI entry. |

Conclusion: Should You Worry About ACPI NSC6001?

The ACPI NSC6001 error is a remnant of computing history—a ghost from the era of National Semiconductor and Windows XP. In 99% of cases, it does not indicate failing hardware. It is simply a driver mismatch between Windows 10/11’s modern power framework and an outdated ACPI table. acpi nsc6001

Driver Version: The standard legacy driver for this device is version 6.0.6001.18000, released around 2006.

In this long-form guide, we will dissect the ACPI NSC6001 from every angle. We will explore its origins in the ACPI standard, its specific hardware association (National Semiconductor), why it causes driver errors, and step-by-step solutions to resolve it.
