Could be a problem with a few things. First, is the power charger stock, or did you buy it separately? Secondly, has it been giving you issues before?

Worst comes to worst you can go into the data recovery mode where you can restore the device to factory settings. To do this, press volume + and volume - at the same time as the power button. Careful though - you'll lose all your data in the restoration process.

Hi, thanks for your reply.
The charger did come with the device.
However, since this problem, I let the device run completly out of power, until it would not even turn on for a second, then plugged in the charger, charged it fully and it is now working ok again. this is the second time this has happened, the first time it only lasted 3 days, which is why I posted the problem.
Is it possible that it crashed, or is it more serious?

"Is it possible that it crashed, or is it more serious?"

Likely whatever battery-monitoring circuit is in the device isn't keeping up with the actual charge on the battery; especially since you mentioned the "-1774182544%" reading. If this is a new device, (if it were me) I'd return it before the warranty runs out if it occurs again.

I have the exact same problem, tablet was working fine. Until the battery ran low and the device switched off. I left it on the charger over night and still wont turn on again. It charged fine every time before that so i know the charger and connection are all good.
The difference being i never let it run all the way down before charging.
This seems to be a common issue that no one has an answer for...
Tried holding vol buttons and power, holding the factory reset button etc etc. But the device doesn't respond at all. There is not even light next to power button...
