Hi there and welcome
When you connect the charger, do you see any recognition on the Tablet of the charger being connected at all?
connect it to your computer please and then tell me if the computer detects it at all.
ok, is it a windows or mac computer and which version?
Click start, computer
In the new window, click on computer and tell me if under devices and drives you see the Tablet there please.
Ok, right click it and select Eject and tell me if when doing this the screen on the tablet now comes on please
The tablet, you said you saw it under devices, so right click it there.
ok, its not detecting it correctly then.
If you click Explore, what do you then see?
ok, it means the mainboard is not at fault
Disconnect it and tell me if it comes on please
It is the internal battery that has faulted. We have ruled out all the other causes
I am really sorry about this and you are going to have to return the Tablet to have this replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the page, then submit, that would be greatly appreciated.
