Why is my laptop not recognizing my touchscreen after waking from sleep mode?

1. Check if the laptop is plugged in. If the laptop is not properly plugged in, the laptop will not be able to access the power needed to use the touchscreen.
2. Update the drivers: It is important to ensure the drivers that power the touchscreen are updated to the latest version.
3. Restart the laptop: restarting the laptop can often help it find the required settings to access the touchscreen.
4. Check the touchscreen settings: Make sure that the touchscreen settings in the laptop's Windows settings are properly enabled.
5. Check for a software issue: sometimes a corrupt or outdated software version can cause issues with the laptop and touchscreen.
