This souns like its either a motherboard issue, battery issue or just a software issue. If its a motherboard issue, then you cant fix it. If its the battery, you can check with the company and see if its still under the warranty, or see how much they would charge to put a new one in it. But before you do all that, try doing a hard reset on the tablet. Make sure the tablet it fully powered down, Press and hold the power up key, and the Power key at the same time. Wait for the recovery mode to show up in the corner. These are just general hard reset instructions, its possible it might not work for this particular tablet. If it doesnt work, then google the nabi dream tab hard reset. and look for a button combination. Hope this was helpful for you.
