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. 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. 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. Restart your computer to make sure the changes take place. From here, you can toggle the HP touchpad settings on or off. Press the Windows button and I at the same time and click (or tab) over to Devices > Touchpad. If this does not work, double-tap the TouchPad on/off indicator as shown in the screenshot below: 8. Therefore, it is always a good idea to confirm that this is not the case. My solution was as others have mentioned. You might need to manually turn on the Touchpad under your settings. Touchpad not working problem can arise if the touchpad is being disabled. 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.
