Hello

Thank you for posting in Q&A forum.

Here are a few steps you can try to resolve the problem:

1. Update BIOS: Ensure your BIOS is up to date. Manufacturers often release updates that fix bugs and add features.
2. Check BIOS Settings: Sometimes, certain settings can cause features to disappear. Go into the BIOS and look for settings related to power management and sleep states. Ensure that the settings for S4/S5 sleep states are correctly configured.
3. Reset BIOS to Default: Try resetting the BIOS to its default settings. This can sometimes resolve issues caused by incorrect configurations. Look for an option to reset to default in the BIOS menu.
4. Disable Fast Startup: Fast Startup can sometimes interfere with sleep settings. Go to Control Panel > Hardware and Sound > Power Options > Choose what the power button does and uncheck Turn on fast startup.
5. Check Wake Events: Ensure that wake events are correctly configured. Go to the BIOS and look for settings related to wake events by USB devices or the OS. Make sure these settings are enabled.
