Everything has passed hardware diagnostics including the touchscreen. All ports, drives, processor, display, memory and the hard drive are working properly. The screen quality is very good. An ac adapter is included. This is a Panasonic Toughbook CF-29 13.3" 40GB, Intel Pentium M, 1.2GHz, 256MB XPP with the 9 pin serial port and the DVD-CDRW optical drive. It is missing the ac adapter port cover, the USB port cover and the nine pin serial port cover. It is ready for use.
