MacBook Air not charging

I have a MacBook Air early 2014 that first had the problem that the battery was not charging. It recognized the battery, but was just not charging. Magsafe light was not turning on/off, so I tried to reset the SMC but didn't help. I removed the battery and then hold the power button for 5 seconds, didn't work as well.

But now I have a new problem, the macbook shuts down after a few seconds when I start the macbook with the battery connected. Macbook works perfectly fine when I remove the battery though.

Any idea if it is the battery, I/O board or logic board?

Replace battery. Match number on battery with battery you buy. A1377, A1405, A1496, etc. MATCH NUMBER!!

This might be the problem. If you can take the bottom cover off your MacBook Air, there is a small sized board to the right of the laptop when you are looking at the bottom with the cover off. There are 2 wires connecting it to the logic board. One on top which is called a ribbon, and one below it. Take one side of the ribbon of of the board and lift it up so you can see the other wires. Check if there is damage to the wires and or if it's un plugged. I hope this helps!

If there is no damage and it's plugged in you should test with a test meter if there's power going through your power cord. If there is test power coming in from the input behind the mag safe connection. E.G the metal prongs attaching the mag safe connection to the board. Then check if power is coming through the wires below the ribbon if you did find power in the other places I mentioned.
