820-3417 fan spins but no green light

[elcapitan]

Hey Guys,

I have a macbook air that spins for 5 second and then shuts off everytime I connect the charger. It does this twice. In the third time it will boot normally. The weirdest part is that it doesnt show any light at the connector. At one point, this board was showing a strong greenlight. Any idea whats going on here? Is my charger bad?

Thanks

Im aware that this is normal behavious for 2013 models (off-on-off-on-off-on) whats the purpose of this behaviour? Should it be showing the green light?
