''What is wrong?''
 
If MagSafe power supply is identified as null and zero, then MacBook embedded controller does not allow charging of main battery.
 
Open 'System Information.app', view 'Power' (subpage of 'Hardware'), look under heading 'AC Charger Information:'. For an idea of what 'AC Charger Information:' looks like, a clue as to what to look for, here is a screenshot. Pictured is a full 'Power' report; near bottom is 'AC Charger Information:'.

If your MagSafesubject power supplyadapter is misidentified, then it might need cleaning or repair. Inspect MagSafe plug pogo pins. If middle pogo pin is dirty or sticky, then clean it or exercise it until it operates as it should. Inspect also MagSafe socket-inlet. If middle pogo pin (in MagSafe tip) is clean and springy, and middle land (in MagSafe inlet) is clean, then your MagSafe plug is at fault.

Get a replacement MagSafe plug or cable assembly, and splice it on. If you cannot find a used Original Apple MagSafe tip, then a non-authorised replica is acceptable. One will be better-off with a counterfeit tip spliced onto genuine power supply, than a knock-off power supply.
