Correct, the touchscreen isn't working. So with a mouse attached no option to add a usb keyboardWhen you say "the unit does not work well with windows 10" what specific problems are occurring?
And, as I understand those tablets, more RAM cannot be added - correct?
I will try to get one tomorrow morning and get back to you. I would like to know how to get the device serial number to find out which device this actual is? Or since I can get into this system, there should be some OS reset option somewhere?Do you have access to a USB hub? Or what about the Surface docking station?
