If the Touchpad is moved, the screen turned on, which used more current than the Touchstone charger could provide, eventually draining the battery to zero charge. Advanced (press and hold the power, center. After a few minutes, reboot your laptop and check if the issue persists. So, press and hold the power button for about 10 seconds and your laptop will turn off. I will note that the situation that led to the problem (in both cases) was sitting the Touchpad on a Touchstone charger with the cover closed. Try all the resets - simple (hold both the power and center button for 15 - 20 seconds until the HP logo appears). The HP laptop touchpad not working problem can also be fixed by restarting the device. When I tried to use a lower current charger, it gave me the 'use the original charger' warning. If the battery is completely dead, try it with a charger connected to it. It flashed the sides of the home button alternately, indicating it was seeing the charger. Hold down the power button while rapidly-pressing the home button about 15 times.

My solution was as others have mentioned. It's as if there is no charger connection to the Touchpad. Note that when the Touchpad is in this weird mode, the charger will NOT get warm when one attempts to charge the Touchpad. I have two Touchpads that had this problem.
