I Bought new Touchpads for my 2 grandchildren Christmas before last. One of the Touchpads I couldn’t charge but after purchasing a new charger made for the HP Touchpad it charged fine. I noticed that when it was fully charged the round plug that plugs into the wall that the USB fits into was warm (almost hot). I bought another charger for my other grandson’s HP Touchpad and have it at my house now. When I plug the charger into the Touchpad, I see the two lights in the lower button flashing back and forth, but it still is not charging or turning on. I also noticed that the round socket is not even warm when plugged into the wall socket. I have reset the round socket to no avail. I have pushed all the buttons at the same time without the Touchpad rebooting and turning on. What can I do now?
