My Samsung galaxy tab 2 7.0 tablet will not respond to anything. It was working fine but I think it died overnight but I'm not sure. It now will not charge, no indicator light showing its charging, no battery on screen, nada. I checked the usb adapter (using the originals that came with it, always have) by attaching my phone charger to it and it works fine, but I do not have a way to check the charging cable. Are there any other suggestions I can try to get this tablet to respond? I am buying a new cable for it today, but it has to ship...
