See the service manual Inspiron 7586 Service Manual (dell.com) If you have never replaced the main battery that could be the problem too. Batteries last only about 2 years nowadays unlike batteries from years ago. There are few real replacement batteries for older laptops now-but lots of scams.

Hello This will be my first time repairing my own laptop. It appears that my charging port is damaged, and I was hoping for some advice on how to repair it. Specifically, I am looking for the type of charging port used by a Dell Inspiron 7586 2 in 1 and any tips on replacing it as well if this is at all possible.  Thanks
