Answer to: HP TouchPad won't turn onI have two Touchpads that had this problem. Note that when the Touchpad is in this weird mode, the charger will NOT get warm when one attempts to charge the Touchpad. It's as if there is no charger connection to the Touchpad. My solution was as others have mentioned. Hold down the power button while rapidly-pressing the home button about 15 times. Then connect the HP wire charger to it. It flashed the sides of the home button alternately, indicating it was seeing the charger. Later, it displayed the battery icon. After that, it boots the OS. If the battery is completely dead, try it with a charger connected to it. When I tried to use a lower current charger, it gave me the "use the original charger" warning. 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. 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.
