Lenovo announced a few hours ago a number of new series ThinkPad notebooks. Among the many new, three stand out for a promise that, if maintained, could not just change our habits for the use of laptop computers and it might also give a boost to the market of the latter against the tablet, provided that the design adequately meets the requirements of lightness and small size.

The new Lenovo ThinkPad notebook T420s, T420 and T520 promise in fact a battery life of up to 30 hours in the configuration of the T420 with an additional 9-cell battery, which was once much higher than that to which we have been used so far.
