This component allows the computer to communicate with older peripherals, such as early smartphones, PDAs, laptops, and certain printers that use infrared light beams rather than radio waves to transfer data.

Since infrared technology is obsolete, having an un-configured device in your Device Manager uses system resources for no reason.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 .
Historically, the NSC6001 hardware ID corresponds to an integrated or a legacy communication chip (such as a Fast Infrared/FIR port or a trusted platform module framework) commonly embedded on the motherboards of older laptops and enterprise desktops—most notably legacy IBM and Lenovo ThinkPad models. Why is it Showing as an "Unknown Device"? acpi nsc6001
The yellow triangle remains, but Windows ignores the device during power transitions. This stops BSODs and slow shutdowns 95% of the time.
Right-click on the "Unknown Device" (ACPI\NSC6001) and select Update driver .
The safest and most reliable way to obtain the verified driver package is through Microsoft's official database. Navigate to the official Microsoft Update Catalog . Search for the keyword . This component allows the computer to communicate with
The NSC6001 has several key features that make it an essential component in modern computer systems:
When you upgrade your operating system, the native Windows Update service often no longer contains the legacy National Semiconductor driver. Therefore, the OS detects the hardware physically connected to the motherboard but lacks the software bridge to communicate with it, leaving you with the dreaded yellow exclamation mark. How to Resolve the ACPI\NSC6001 Issue
The 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 Open the
Before Wi-Fi and Bluetooth became universal standards, laptops like the used this chip to communicate wirelessly over short distances. It allowed computers to sync data with early smartphones, personal digital assistants (PDAs), and compatible printers at speeds up to 4 Mbps.
Based on the hardware ID ACPI\NSC6001 , this guide will help you identify, troubleshoot, and install the correct driver for this device.
