send it for warranty repair

It could be the battery is already on its end of life. Could be, your charger can't deliver enough power to work and charge the tablet. Before you start worrying, please leave the tablet on a charger over night, with everything switched off. Then remove it from the charger and start it. If you keep having the same problem, and you can't check the quality of the battery, start saving for a new tablet. Not worth paying 100 dollar for replacing the battery, if you can buy a new tablet for the same price. If you can open the tablet, check if the battery is still connected correct.

Can mean the battery isn't communicating its status to the tablet--failing battery, bad connection, etc. Talk to tech support for a replacement if it's still under warranty. If it's not and you can still charge it to 100%, hang on and hope for the best.

all I cant suggest if its still under warranty take it back to place of purchase,my flatmates boy had same problem the guy at the shop where it was brought from fix it in about 2minutes and no charge .
