Has faulty backlight, but runs great with another monitor. All keys, Disk Drive, and track pad has been tested and is working perfectly. Some dings in body. See photos as they are part of the description. The back light will come on from time to time, but is HIGHLY unreliable. You will need to repair the back light or use a second monitor. Other than the monitor this computer operated as it should.
