ERROR_ACPI_ERROR
What ERROR_ACPI_ERROR means
ACPI is the firmware interface Windows uses for power management, device discovery, sleep states, batteries, thermal zones, and platform controls. A failure here often reflects firmware tables or AML methods rather than an ordinary application problem.
Where it appears
- boot or device enumeration
- sleep, resume, hibernation, and shutdown
- battery, thermal, lid, docking, or power-policy changes
Likely causes
- invalid or incompatible BIOS/UEFI ACPI tables
- firmware methods returning malformed values
- chipset or platform driver mismatch
- virtual-machine firmware exposing incomplete ACPI behavior
What to collect
- System log entries from ACPI, Kernel-Power, and related providers
- BIOS/UEFI version and machine model
- sleep-study or powercfg reports when transitions fail
- whether the problem began after firmware, chipset, or OS updates
How to respond
Install the vendor-supported firmware and chipset packages, reset unsupported firmware tuning, and reproduce on the current BIOS. For virtual machines, update the hypervisor tools and virtual hardware level. Application retries cannot repair malformed ACPI firmware.
