Hello guys I just been reading this thread saying to God down the volume up button and the power button down at the same time.. tried that and different buttons but none seem to be working.. it is plugged in, sometimes the tab even vibrates when I press a combo of buttons
It may well be on then, or turning on, but the display isn't. Try this first...
Try the following and see if it will turn on.
1. Remove the battery.
2. Press and hold the "Power" button for 20 seconds.
3. Now put the battery back in.
4. Plug it in to charge and allow it to fully charge before turning it on.
If this doesn't help, then test the charger cord to see if it is good. Either try your cord in another device, or try another devices cord on your device.
Should that not be the problem, then check the battery to see if it needs replacing.
NOTE: Yes, I know tablet batteries are not so easy to get to, on some devices. In such a case, make sure that your tablet is not under warranty still before you try opening it up yourself. If it is under warranty, then contact the manufacturer first.
