Replace the chord from the wall it is probably the fuse in the chord. Universal chargers are cheaper than they were a few years ago. You can check the recall status it might be free. Make sure it isn't trying to charge wirelessly if that doesn't work
Check the chord from the wall if there is a fuse blown in the chord it can be fixed by getting a new one or universal chargers have become cheaper lately. They did have a lot of recalls on chords and batteries. I had this problem on three laptops.
