Make sure that the laptop touchpad has not accidentally been turned off or disabled. You might have disabled your touchpad on accident, in which case you will need to check to make sure and if needed, enable the HP touchpad again.

The most common solution will be to double tap the top left corner of your touchpad. If you see a small glowing orange light, this usually indicates that the touchpad is not working and has been disabled.
