Lenovo black screen and do not show charging

I have a huge problem with my lenovo B5400 with Win7. On the power adapter without battery it works ok. But when I plug in the battery and it is charging, Windows does not show the charging icon, but when the battery is at 100%, the screen goes black and the fan goes to 100% and the shutdown button stops responding, the only way to shut down the laptop is to pull out the battery. I thought it was the battery (its from 2014), but I ordered a replacement and the same thing is happening. What could be wrong? KBC?

This question is one of 3 reports of the same problem:

Why am I getting a black screen issue on a Lenovo LOQ laptop?
