Updated: Feb 21, 2026
Technical Meaning
The ERROR_HIBERNATION_FAILURE error code, with the numeric value 656 and hexadecimal representation of 0x290, indicates that the system has encountered an issue while attempting to hibernate. This failure prevents the system from entering a state where all running processes are saved to disk, allowing for quick resumption after a power loss or reboot.
Error Details
The error message states: 'The system has failed to hibernate (The error code is %hs). Hibernation will be disabled until the system is restarted.' This message suggests that the system has halted its attempt to save state data and will not allow hibernation until a restart occurs.
Usage Context
This error can occur in various scenarios, such as when the system detects an issue with critical files or directories required for hibernation. It may also be triggered by hardware limitations or software conflicts that prevent the necessary operations from completing successfully.
Developer Interpretation
Developers should interpret this error code to indicate a failure during the hibernation process, which could result in data loss if the system loses power unexpectedly before fully entering hibernation. The developer must ensure that all critical state is saved and that no processes are left running when attempting to hibernate.
Related Errors
ERROR_DISK_FULL(28): Indicates insufficient disk space for saving hibernation files.ERROR_INVALID_PARAMETER(1206): Suggests a parameter passed during the hibernation process was invalid or unsupported.ERROR_FILE_NOT_FOUND(2): Implies that a required file or directory is missing, preventing hibernation.
FAQ
Q: What does ERROR_HIBERNATION_FAILURE mean?
A: It indicates that the system failed to properly save state data for hibernation and will not allow hibernation until the issue is resolved.
Q: How can I resolve this error?
A: Restart the system, which will disable hibernation temporarily. Once restarted, attempt to hibernate again; if the issue persists, check for hardware or software conflicts that may be preventing hibernation.
Summary
The ERROR_HIBERNATION_FAILURE error code signifies a failure during the hibernation process and requires a system restart before hibernation can be attempted again. Developers should ensure all critical state is saved properly to avoid data loss in such scenarios.
