MacBook Pro not powering on (with green flash on magsafe for one time)?

So as my question indicates my macbook pro (2014) not powering on, when i plug the magsafe adapter the little green dot flashes once!

it happened all of the sudden, it was working fine, I was using the laptop when i saw it needs to be charged I plugged the adapter and as I described, green flash led once and it wasn’t charging! I unplugged it and plugged it a couple of times but same result. So I tried to reboot it and that’s when it just died.

it keeps showing me drained battery on screen (the normal logo you get on screen when you try to turn on your mac when battery is dead) and same thing when plugging the magsafe over and over.

Please help.

Please note that both battery and adapter has been changed last year at apple.
