MagSafe Connector on MBP is not lighting (battery is working)

Hi, when I connect the magnetic MagSafe connector to my MBP (upper left of MBP), there are no lights coming on (no orange/green) - it went out today. The battery was replaced last year by me along with upgrading the RAM to 16gb and installed a 500gb SSD. The MBP powers up just fine. I also recently replaced the Apple Genuine MagSafe Power Adapter 2 months ago. Software is updated for this model/year.

Right now I am using what’s left of my battery charge and it is quickly diminishing (I have a hotspot connection). Question - I don’t know if I should try to replace the MagSafe Connector (I think the part is under $20 on your site) or just throw in the towel and buy a new MBP. Any thoughts?? Again, I am working intermittently with a diminishing battery. Thanks to all in advance. Mary.
