Hey, this side is Marry alen working in Technical Support. If your HP Laptop Touchpad Not Working, try these. Verify that the touchpad on the laptop has not been unintentionally deactivated or switched off. You should double-check to be sure and re-enable the HP touchpad if necessary because you might have accidentally disabled it. Another possibility is that your computer just needs to reboot. Attempt to restart your computer right away if you haven't already. The drivers for your touchpad may need to be updated if not.
