If your MacBook Air is not going to sleep as expected, there are several potential solutions you can explore based on various sources.

1. Check Sleep Settings: Ensure that your sleep settings are correctly configured. You can navigate to Apple menu > System Settings, then click on “Lock Screen” to set how long the Mac should wait before going to sleep after inactivity. It’s also suggested to check the Energy Saver settings (Apple menu > System Preferences > Battery or Energy Saver) to ensure that the display is set to turn off after a reasonable duration and that the sleep option is enabled. For detailed guidance, refer to the Apple Support page on setting sleep and wake settings for Mac.

2. Prevent Automatic Sleep Issues: Sometimes, the feature “Prevent automatic sleeping when the display is off” can cause issues. It's advisable to turn this feature off and allow the display to turn off separately. According to discussions in the Apple Support Communities, this can help restore proper sleep functionality.

3. Activity Monitor Check: Occasionally, background processes can prevent your Mac from sleeping. Use the Activity Monitor to check for any processes that may be stuck and require force quitting. Similar tips on troubleshooting can be found on $this Reddit thread.

4. Lock Screen and App Settings: Ensure your Lock Screen settings are not blocking the sleep mode. Apps that use App Nap can sometimes interfere with sleep. Refer to MacPaw’s troubleshooting guide for further steps on managing these settings.

5. Consulting Troubleshooting Guides: Numerous troubleshooting articles and community discussions are available to guide you through the process of resolving sleep issues. For example, EaseUS outlines seven proven methods to fix sleep issues.

By following these steps and guidelines, you should be able to resolve the issue of your MacBook Air not going to sleep. If the problem persists beyond these common fixes, it may be beneficial to reach out to Apple Support for further assistance.
