While sounds like a modern error, it is actually a legacy identifier for one of the most successful processor architectures in history. If you are still running this hardware today, it is a testament to the longevity of the Core 2 Duo era.
The OS cannot enter deep C-states (C3/C4) due to an incorrect ACPI _CST object. Solution: In Linux, add processor.max_cstate=2 to GRUB kernel parameters. In Windows, install the latest chipset driver from Intel (INF update). Acpi Genuineintel---intel64-family-6-model-15
is an open industry standard that allows your operating system (like Windows or Linux) to talk to your hardware [25, 29]. It acts as a "power maestro," handling critical tasks like: Sleep and Hibernation : Managing how your computer enters low-power states [26]. Hardware Discovery
The identifier refers to an Intel Core 2 Duo or Core 2 Quad processor , typically from the "Conroe" or "Kentsfield" architecture released around 2006–2007. | Feature | Details | |---------|---------| | |
Most users only encounter this specific string when something goes wrong. Here are the two most common scenarios: 1. The "Yellow Exclamation Mark" in Device Manager
ACPI is the standard that allows your operating system to communicate with the motherboard and hardware for power management and configuration. When this string appears, it typically lives in the ACPI _UID (Unique IDentifier) or a namespace path like \_SB_.PR.CPU0 . The OS queries ACPI tables to identify the processor type before loading the correct drivers. Solution: In Linux, add processor
– The specific model number within family 6. Model 15 (0x0F) corresponds to:
