Sony Vaio Charger light blinking, won't turn on.

Hi everyone, I need your help urgently!

I have sony Vaio laptop which has been working well. Recently its charger had a minor explosion and broke (it happened when I plug it in to the outlet as usual). So I replaced it with a new one. However, the light on the new charger was blinking whenever I plug it into the laptop and turned solid again when I unplug it.

Could you please help me fix this? All my assignments and works are in this laptop and I need it very soon.

Thank you

Ps. I have tried removing the battery and it still doesn't work. Also I won't be able to try another charger.
