I've given up trying to solve this. Decided to just ditch dell laptops altogether because of the lack of help with this issue. Thanks for nothing 
Did a BIOS update on my  Inspiron 3593 and now the BIOS says that the ac adapter isn't installed and because of that it won't charge. I have absolutely no idea how to fix this. Can someone please help? I've tried uninstalling the battery driver from the device manager thing and letting it reinstall but that didn't help at all.
