Before you spend money on a new charger or even a new battery & well before you consider taking your tablet apart to touch or solder anything try this that I read on a different post on this site. First disconnect your tablet from the power cord. Then hold down the on/off button for 30 seconds & while STILL HOLDING DOWN the POWER BUTTON, SLOWLY insert the power cable. Continue to hold down the power button for up to 30 seconds, AND VOILA, PRESTO, it was fixed WITHOUT taking the Tablet apart, WITHOUT spending a dime or even a penny!!!
