Powerful Business class laptops, Solid steel frames, new design and very tough. Min. 4 gb Ram and second gen+ processors, these quad thread laptops can handle anything. Equipped with HDMI port for instant media center. I have these available in regular Intel graphics, and Nvidia Quadro Graphics for those who need a machine capable of higher than average graphics use. The E6220 have backlit keyboards and are a very portable 12" full spec laptop These machines are mostly 400, a few are 450 and 500 (higher specs and duo video cards). Warranty included.
