This is a desktop replacement Laptop. It has one Pentium 4 2.8GH processor. with 2GB Ram, and either a 140GB, 5400 RPM or 80GB 7200 RPM Hard drive.

A docking station will be included for the additional cost of shipping ~ $10. I have completely refurbished these computers, inside and out. They are set up with Dual operating Systems; Windows XP (default), and Windows 7. You have 10 seconds to select which one you want to use at startup. Win 7 can be used for the internet with MS Edge, or Firefox. You can also capture and convert Music from the internet with VLC & Roxio. Complete Office 2007 with all updates and Photoshop are installed as well. Windows XP is installed because it has a unique program called Giga-Pocket personal Video Recorder. This program allows you to easily convert any analog video from VHS, Video 8, etc to a Digital  (DVD) format. The special Sony I/O video composite cable is also included. You will use this operating system to watch DVDs and convert captured video to digital format. Use included Roxio to burn homemade DVDs.The instructions are included in the User Manual provided on the computer.
