RazerBlade Pro 17' 2017 charger issues. No power to the laptop

Hello, excuse my english. I'm not fluent. I have a bought a RazerBlade pro 17' 2017 on amazon about few months ago. The laptop is in pristine condition and i use or for casual gaming. Not hardcore at all with session of 3/4 hours. Since yesterday the charger does not give power to the laptop anymore. I try everything and the charger seems working cause I can see the green light. The laptop is not giving any light when plugged to the charger. The laptop seems ok, but there IS no more power in battery so I can't even start it. Anyone Can help me ? My guess is either the charger or the battery has a problème but I dont really know. Might be the charger but how that happened ? One day to another, everything working then suddenly there IS no power given to the laptop. Should I buy a new charger ? Where, i dont sée them anywhere on the net. Thanks to help me, Cheers. Elie.
