ERROR_SYSTEM_POWERSTATE_COMPLEX_TRANSITION - 783 (0x30F)
The system power state is transitioning from %2 to %3 but could enter %4.
Updated: Feb 21, 2026
Technical Meaning
This error code indicates a complex state transition issue within the Windows operating system. Specifically, it suggests that the system is attempting to transition from one power state to another but encounters an unexpected condition that prevents it from entering the intended target state.
Error Details
The error message states: 'The system power state is transitioning from %2 to %3 but could enter %4.' This implies that during a power state change, the system identifies a scenario where it cannot directly transition to the desired state and may need to take an alternative path or fail the operation.
Usage Context
This error code can be encountered in various scenarios involving power management within Windows. It is particularly relevant for developers working with power-related APIs such as SetSystemPowerState or WmiPowerManagement. The error might also appear during system shutdown, hibernation, or resume operations where complex state transitions are involved.
Developer Interpretation
Developers should interpret this error code as an indication that the current operation to change the power state is encountering a condition that prevents it from proceeding directly to the intended target. This could be due to various factors such as system constraints, hardware limitations, or software conflicts. Developers may need to handle such errors by retrying the operation with appropriate context or adjusting the parameters to ensure compliance with system requirements.
