Dell Inspiron 15-3552 issues

Hello all,

I've had my Dell Inspiron 15-3552 for a few years now. A few months back, it began to beep 5 times on start up, continuously, until the laptop fully booted up. I replaced the CMOS battery, nothing, still beeps. Then I got an error saying the actual laptop battery was bad. I replaced that yesterday, and though the battery is brand new and took away that error message, now I'm getting this one:

"The AC power adapter wattage and type cannot be determined.

The battery may not charge.

The system will adjust the performance to match the power available.

Please connect a Dell 45W AC adapter or greater for the best system performance."

I have tried two chargers, both of which seem to work fine (green light comes on on the power brick), but the charger port itself seems very wiggly when I plug the charger in. The port looks a tad bit damaged. Could that be what's causing all of this trouble? Would replacing the port fix the issue? It's super frustrating.
