Battery that lasts as long as you do. Stay unplugged and on-the-go all day with a multitude of battery options for your X220. Get up to 15 hours with ThinkPad 29++ slice battery, but if that isn't long enough to keep your engine roaring, also attach the slim, external ThinkPad 19+ slice battery for up to 23 hours of juice. Continue to optimize your X220's lasting performance with our Low Power Multimedia Mode and Power Manager utilities. Intelligent design. We went feather-light on the weight (starting at under three pounds), but we still loaded the X220 with heavy usability features. Type more comfortably and accurately with a 45% larger, buttonless touchpad design on our industry-leading Thinkpad keyboard. Rely on our premium durability standards and Active Protection System™ to provide a rock-solid machine, which now includes a redesigned hinge with stronger magnetic-latching support.
