This is a good working laptop with 15.4 ins screen in perfect working order. It is running a legitimate upgrade of Vista Enterprise and I will provide the DVD with the Operating System and product key number. I will also provide the DVD with Windows seven from HP, and another DVD with the drivers, but I don't have the product key for Windows 7.-160gb hard drive-2gb memory-DVD burner-Webcam-Full keyboard with number padCosmetically it is in great shape, not perfect.The battery was acting weird when I had Windows seven on it
