Hi Veronica,

Have you got access to another compatible charger? If so try it and see if the tablet responds in any way. If it does your charger is faulty and needs to be replaced. If you don't have another charger, you can try connecting it to a PC. It will not charge effectively but it may give an indication that it is alive. If it does, disconnect it from the PC and then purchase a replacement charger. You could also go to a store where they sell chargers and ask if you could try one, a charger that is, off their display models to verify that yours is faulty. It never hurts to ask.

If it doesn't respond at all check to see if your warranty period is still valid and if so contact the manufacturer's customer support section regarding a warranty repair.
