Updated: Feb 21, 2026

Technical Meaning

The ERROR_HIBERNATED error code, represented as 726 in decimal and 0x2D6 in hexadecimal, indicates that the system was put into a hibernation state. This typically occurs when the system is shut down by saving the current state to disk before entering a low-power mode.

Error Details

This error code does not represent an error condition but rather a normal system behavior. It is often returned in scenarios where the operating system needs to indicate that it has completed hibernation and is now ready for further operations.

Usage Context

The ERROR_HIBERNATED error code can be encountered in various contexts, such as:

  • During the initialization of a system service or application after a hibernation event.
  • In certain APIs that query the current state of the system.
  • When handling events related to power management and system shutdowns.

Developer Interpretation

Developers should interpret this error code as an informational message rather than an indication of failure. It is useful for applications that need to synchronize their state with the system after a hibernation event or when performing operations that depend on the current system state.

Related Errors

  • ERROR_NOT_READY (0x5): Indicates that the system is not in a ready state, which could be related but distinct from ERROR_HIBERNATED depending on the context.
  • ERROR_INVALID_PARAMETER (0x57): May occur if an operation was attempted with invalid parameters after hibernation.
