Dell Inspiron 3558 power problem

My Dell Inspiron 3558 is about 4 years old now and when I try to charge it, it will not charge. I've opened it up and noticed the power jack was loose and it was a screw that broke that made it loose. I think it's the battery because when I boot with the battery it doesn't boot all the way and shuts down, but when I boot without the battery, it boots properly and another thing I noticed was that it gave me a message saying that the charger couldn't be recognized but I was using the charger that came with it. I've tried cleaning the pins for the battery on the laptop but that didn't work. So the problem might be the power jack, battery, charger, or something else possibly.
