ThinkPad T420s is mainly to convince business customers of its advantages as a powerful and yet portable companion. Equipped with a Core i7-2520M, Lenovo has created good prerequisites for this venture.Hardly another notebook range in the business sector enjoys such a high reputation as the ThinkPad models from Lenovo. The greatest robustness, high performance hardware and long battery runtimes are the qualities that let the manufacturer of the T series especially stand out.The T420s is a lot lighter and compacter than the previously reviewed T420 despite the same 14 inch size.
The T420s looks considerably slimmer and less unwieldy than its otherwise largely identical brother, T420. This is due to a weight of about 1.7 kg and an overall height reduction of about 0.5 centimeters. Lenovo has also maintained the classic ThinkPad design in the newest scion of its notebook range. Its appearance is dominated by plain but extremely robust, black plastic, reinforced with carbon fiber and magnesium, as in the past. The manufacturing quality is almost immaculate. We couldn't find any irregular gaps or deficient material transitions.
