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
Evidence 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.
Diagnostic interpretation
For this particular status, the decisive evidence is System log entries from ACPI, Kernel-Power, and related providers, BIOS/UEFI version and machine model. Those details separate the documented condition from unrelated failures that happen to occur nearby.
Record the numeric code together with the symbolic name ERROR_ACPI_ERROR, the API or subsystem that produced it, and the first preceding failure. A later cleanup occurrence may describe a consequence instead of the initiating defect.
Example
A diagnostic trace records this result after an operation changes subsystem state. The result investigation should follow the first state-changing call, validate its resulting state, and classify later cleanup messages as secondary evidence.
Implementation guidance
Code handling this result should distinguish a terminal failure from a warning, progress indication, or request to repeat after a defined state change. When handling it, preserve handles and output fields only where the originating API explicitly keeps them valid. The path needs bounded retries and cleanup that tolerates partial initialization.
Validation after remediation
Repeat one controlled operation that previously produced this result. Verify both disappearance of the status and completion of the specific state transition described above. Adjacent messages around it must also be reviewed so a fallback is not mistaken for a complete repair.
