Welcome to the Community Forums.
Try to isolate the point of failure making sure that this is not because of the ac charger and cable. Check if any indicator light shows up (power and battery led ) or blinks when connected with a known good charger.
Examine if there is any physical issue on the dc in port. Have the machine checked further through your local service center specially if the charger works ok.
Update us how it goes.
