ERROR_DRIVER_FAILED_SLEEP - 633 (0x279)

Technical Background

The ERROR_DRIVER_FAILED_SLEEP error (633, 0x279) is a specific error code indicating that the system failed to enter standby mode due to an unsupported driver. This error suggests that one or more drivers do not support the necessary operations required for the system to transition into a low-power state.

Error Details

The error message {System Standby Failed} The driver %hs does not support standby mode. Updating this driver may allow the system to go to standby mode. provides context about the issue and suggests potential solutions, such as updating the affected drivers.

Common Causes

• Unsupported Operations: The driver in question does not implement the necessary APIs or functions required for entering sleep modes.
• Driver Bugs or Incompatibilities: A bug within the driver code that prevents it from properly handling the sleep state transition.
• Outdated Drivers: The installed version of the driver is outdated and lacks support for modern power management features.

Real-World Context

This error typically occurs when a user attempts to put their Windows system into standby mode, but encounters issues due to unsupported drivers. It can affect both desktop and laptop systems depending on the specific hardware configuration and the drivers installed.

Is This Error Critical?

The criticality of this error depends on the impact it has on the system's ability to enter a low-power state. While not immediately critical for system stability, it may lead to increased power consumption or reduced battery life in mobile devices.

How to Diagnose

Reviewing Operation Context

• Check if any specific applications or services are running that might interfere with the sleep process.
• Verify the current driver versions and ensure they are up-to-date.

Validating Parameters

• Ensure all parameters passed to power management APIs are valid and correctly formatted.

Confirming Object Types

• Identify which drivers do not support standby mode by checking system logs or using diagnostic tools like Device Manager.

How to Resolve

Correct Parameter Usage

• Update the affected drivers to versions that support sleep modes. This can often be done through Windows Update or downloading the latest driver from the manufacturer's website.
• Ensure all parameters used in power management calls are correct and up-to-date.

Adjust Operation Context

• If certain applications or services are causing issues, disable them temporarily to see if they are responsible for the error.
• Check system settings related to power management to ensure they are configured correctly.

Developer Notes

Developers should be aware that ensuring compatibility with sleep modes is crucial for maintaining a good user experience and optimizing power consumption. It is recommended to thoroughly test drivers in various power states during development and update them as necessary to support modern power management features.

Related Errors

• ERROR_POWER_FAILURE (0x9A): Indicates a failure in the power subsystem, which may be related but not directly caused by driver issues.
• ERROR_INVALID_PARAMETER (0x57): May indicate that an invalid parameter was passed to a power management function, leading to similar symptoms.

FAQ

Q: Why does my system fail to enter standby mode?

A: The error indicates that one or more drivers do not support the necessary operations for entering sleep modes. Ensure all drivers are up-to-date and compatible with your system's requirements.

Q: How can I resolve this issue?

A: Update the affected drivers, check system settings related to power management, and ensure all parameters used in power management calls are correct.

Summary

The ERROR_DRIVER_FAILED_SLEEP error (633) is a specific indication that one or more drivers do not support entering standby mode. This can be resolved by updating the affected drivers and ensuring proper configuration of system settings related to power management.
