I opened my laptop yesterday and got a message saying battery 2 the battery is not detected try reinstalling or recharging the battery to solve the problem" So i restarted my computer and everything was fine even charged my laptop. Then today i got the same message and when i opened my laptop and now the second battery will not charge. I restarted my computer, downloaded all of the drivers and still nothing. The lenovo x250 has two batteries and it is the external one not the internal battery. Without the second battery the laptop only lasts about 2 to 3 hours max any help please
