Isperion 15 5000 series model 5558

Computer will not power up from charger or charge the battery which is now fully discharged. I did the battery reset and the charger is working properly. I tried a charger of the same specs as the original and it still does not power up. Is there anything else I can do to get this powered up. The laptop did run until the battery was discharged.

Dell has exchanged it for a new laptop, so no longer an issue with me, just hope new one is not a dud..
