Acpi 80860f14 [patched] -

Most modern kernels (5.x and above) automatically handle this ACPI ID. "Is this a hardware failure?" No. The presence of ACPI\80860F14 in Device Manager does not indicate a broken component.

Introduction: The Mystery of the Device Manager Exclamation Mark If you have ever ventured into the Device Manager on a Windows tablet, a low-power laptop, or an embedded Intel system—only to be greeted by a yellow exclamation mark next to an unknown device with the hardware ID ACPI\80860F14 —you are not alone. Most modern kernels (5
