This is the most severe symptom. Windows attempts to put the legacy NSC device into a low-power state (D3), but the device either doesn't respond or the driver lacks proper power management hooks. The result: a Blue Screen with bug check code 0x0000009F .
The NSC6001 is a hardware component that acts as a bridge between the system's hardware and the ACPI software. It is responsible for managing power consumption, monitoring system temperatures, and controlling system configuration. The NSC6001 communicates with the system's BIOS (Basic Input/Output System) and operating system to provide a seamless power management and configuration experience.
Windows 10/11 does not have built-in drivers for 2000-era infrared ports. acpi nsc6001
There are three main methods to resolve the missing driver issue.
To resolve the driver issue, it helps to understand what this hardware string means: This is the most severe symptom
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.
: You can sometimes force a "Standard Infrared Port" driver via the "Let me pick from a list of device drivers" option in Windows, though its utility is purely cosmetic in 2026. Running Windows 7 on a Fujitsu Siemens Amilo Pro V8010 The NSC6001 is a hardware component that acts
If you are looking at your Windows Device Manager and seeing an error for a device labeled or *NSC6001 , you are likely dealing with an issue related to an older hardware component. This error often appears as "Unknown Device" or a device with a yellow exclamation mark after a Windows update or a clean install of Windows 10 or 11.
In the sleek, power-managed world of a modern computer, the Advanced Configuration and Power Interface (ACPI) is the unseen orchestra conductor. It choreographs the sleep states, the fan speeds, the CPU throttling—a silent ballet of energy efficiency. But buried within the ACPI namespace of certain embedded and industrial motherboards lies a peculiar device: ACPI0004 (often with a specific HID of NSC6001 ). To the casual user, it’s an anonymous driver entry. To the hardware archaeologist, it is a ghost in the machine —a deliberate, fascinating bridge connecting the 64-bit, multi-core present to the 8-bit, 4.77 MHz dawn of the IBM PC.
When upgrading these legacy systems to newer operating systems like Windows 10 or Windows 11, this component frequently appears as an in Device Manager because modern operating systems no longer pack the driver by default. Understanding the ACPI\NSC6001 Hardware ID
