Windows knows the hardware is there but doesn't have the specific "map" to talk to it. You can usually fix this by visiting the Intel Driver & Support Assistant to automatically find the right chipset software. Intel Management Engine (ME):
Model 58 brought several major technological changes to the market: acpi genuineintel---intel64-family-6-model-58
This article will dissect every part of this identifier, explain how it appears in system logs, what hardware it refers to, and why it matters for OS developers, power management engineers, and Linux enthusiasts.
Use Intel's Graphics Driver for Windows 15.45 to check for updates. ACPI \ GenuineIntel _-_ Intel64 _ Family 6
instruction (Intel Secure Key) for high-quality, hardware-based cryptography. Identification Context In ACPI and Windows Device Manager strings:
This is the most hardware-specific part. Intel assigns a (major generation) and model (specific core design) to every processor. Family 6 has been used since the Pentium Pro (1995) for almost all recent Intel Core, Xeon, Atom, and Celeron processors. Model 58 (decimal) or 0x3A (hex) corresponds to: Use Intel's Graphics Driver for Windows 15
[Describe exactly what is happening. For example: "The system is experiencing frequent WHEA errors" or "I am looking for compatible graphics drivers for Windows 10."] Steps Already Taken:
Fast Startup causes many ACPI issues on older hardware because it saves a "hybrid" sleep state rather than shutting down completely. Open . Go to Power Options > Choose what the power buttons do . Click "Change settings that are currently unavailable." Uncheck Turn on fast startup (recommended) . Click Save changes and restart. 4. Update or Reinstall Intel HD Graphics 4000 Drivers
Some hypervisors (especially buggy KVM or QEMU defaults) pass an incomplete or manually mangled ACPI processor object. The triple-dash ( --- ) is abnormal; it likely denotes a from printk formatting or a malformed DSDT. On real Ivy Bridge hardware, you should see a clean "ACPI: GenuineIntel (Family 6 Model 58)" without dashes.
To fix issues related to this identifier, it helps to decode exactly what the string means:
