   If the option doesn't appear, tap 'Change settings currently unavailable' and check (or uncheck) the hibernation box.

These actions often resolve suspension issues for many users. If after adjusting these options the computer still won't go to sleep, continue with the following methods.

Disabling Fast Startup: Does It Really Help?

In Windows 11 (and earlier versions), the feature quick start It is designed to accelerate the Boot, But Paradoxically, it can interfere with the proper functioning of the suspension., especially on older computers or those with incompatible hardware. To disable it:

1. Access 'Power Options' from the Control Panel.
