Hello
The NoMultiStageResumeReason registry entry you mentioned is a diagnostic field used by Windows to indicate why a multi-stage resume was not used during the system’s resume from hibernation. The value 0x4 doesn’t have a publicly documented meaning, and it’s difficult to provide a precise explanation without more context.
The multi-stage resume process is an optimization that can improve resume times on systems with large amounts of memory. If your system is not using a multi-stage resume, it could be due to a variety of factors, including system configuration, hardware capabilities, or driver issues.
To troubleshoot this issue, you might want to consider the following steps:
Update your system: Ensure your system is up-to-date with the latest Windows updates, as well as updates for your hardware drivers. This can often resolve issues related to system performance and compatibility.
Check for software conflicts: Sometimes, certain software or drivers can interfere with the system’s ability to effectively manage power states. You might want to check if disabling or uninstalling any recently installed software or drivers improves the situation.
Hardware troubleshooting: In some cases, hardware issues can affect the system’s power management capabilities. If you have recently added or changed any hardware components, you might want to investigate if these changes are related to the issue.
System settings: Check your system’s power management settings in the Control Panel to ensure they are correctly configured for your needs.
