what charger is for real
Posted on 2014-04-17
I have the new T440S laptops from Lenovo and there is a huge difference on what is supposed to be the correct power charger and what really works. I also notice the connector on the end is square. Now my question is, what size wattage should truly be used, 67, 90, 135, 170? It seems that if you use the smaller below 90 it will not support 2 monitors. I have found also that it may be a docking station firmware issue? The W series 540 and above uses the big brick and it is big, 170 and 190 Watt. Why they just don't leave things alone scares me.
