If the display on my laptop is not turning off when in tablet mode, here are the steps I should take to troubleshoot the issue:

1. Check your laptop’s configuration settings for any power settings that may be affecting the display.
2. Restart the device to ensure any settings changes were properly applied.
3. Check if your laptop has an automatic display sleep setting that needs to be disabled.
4. Update the laptop’s device drivers to ensure compatibility.
5. If the issue persists, reach out to your device’s technical support team.
