You state the MagSafe charger is working but you didn’t tell us what the color of the LED is it Amber or Green when you plug it in. Is the cord and the connector in good shape? Check out this Apple T/N [https://support.apple.com/en-us/HT203207|Apple Portables: Troubleshooting MagSafe adapters] Make sure you have the correct charger and the connections are good. If it’s not lighting then your DC-In board likely needs replacing (inspect it first). You should also check the onboard battery checker which will tell you the batteries charge & health. How many of the LED are lit? Are then blinking or steadily lit? Lets start there before we go forward with anything deeper.
