Battery plugged in, not charging (Latitude)

I've tried all on the Dell Thread. Temporary fixes from plugging the adaptor in after power up, release charge and remove battery overnight, clean jack and plug and check for recognized signal etc., update BIOS, reinstall drivers, Changing BIOS to ignore charging (which I don't have the option), ran Dell Diagnostics, ran System File Checker (SFC).... 

Two things. The Balun on the power cord is typically what goes bad (the cylinder looking thing). It's cheap part when you find out what it is and how it's made). Nuff of that though. F2 to bring up BIOS, selected Express Charging (Power) to Standard Power. I don't have a problem anymore.
