This computer is ready to use straight out of the box. It has gone through a thorough a rigorous refurbishing process as well as Quality Control Testing. First, we erased all of the previously stored data according to DOD standards. Then, we replaced any failing or bad hardware including the hard drive, memory and capacitors. We have verified that all of the ports and connectors are in proper working order.
