Question Dell Latitude 7202 or 72xx Series USB & Touch Screen Not Working

Every now and then I need this Tablet PC where a regular laptop will not do.

When the batteries are near depleted after sitting for a while I usually get a Date and Time reset message.

When I turn it on the message came up, but I could do nothing when I got into the firmware. The Touch screen would not work. I tried a USB Keyboard and Mouse, neither of them could get power from the USB port.

I am at a complete loss of what to do as I have no means of input.

I am assuming something happened to the USB channel and the touch screen does not work as it is more than likely routed through the USB channel.

Any input from any members would be appreciated.
