My lenovo T410 went dead suddenly just after booting to the Windows logon screen. All was well when I powered down a few hours earlier. Now there is not even a charge indicater light when pluged in. I tried every thing removable ect. in my partners identical machine (stock machines purchaced together for incentive) and the battery, charger, memory all work fine in his machine while his "parts" do nothing for my situation. The only thing different is I'm running Windows Insider preview builds. However the machine had been running fine after the latest build was installed. I reall love this laptop and would like to keep using it while awaiting new tec. to become available in 2017. Some of you will know what I mean...! Any help or sugestions ...most gratefull.
