Attention to detail.
We took the no-nonsense business side of the ThinkPad and added a touch of personality for customer-facing roles in small- to medium-sized businesses. The result? A slimmed down laptop — it's 13 percent thinner than previous generations — wrapped in a refined, soft matte finish (available in Heatwave Red or Midnight Black) and reinforced with sturdy metal hinges. We also upgraded our legendary spill-resistant keyboard with a numeric keypad (available on the E520) and made sure our multitouch touchpad would be large enough for the most comfortable typing and data-entry experience possible. You can rely on these laptops' design for durability and security, too. Our Active Protection System™ will keep your hard drive safe when you are on the move.
