Hey There, I am Pol Smith. By Updating drivers and restarting the laptop you can easily solve the touchpad issue. Another possible solution to resolve this issue is to check if the touchpad is enabled in the device settings. If it is enabled in the setting then try reinstalling the touchpad drivers from HP websites. If again the problem doesn’t get solved then contact HP Support for further assistance. There could be hardware issues so get in touch with the customer care team.
