My tablet did it again. when my tablet is open 24 hours there's no problem works properly 

but yesterday i turned off for a few hours and after i couldn't open again.  The Battery had fully discharged. 

I think is a Battery Problem

Hi again e_v_rything1,

Do you mean that the tablet drained battery even when it was powered OFF? Perhaps, you should try uliwoolys suggestion again. If the battery is completely flat, it can take a longer time before the unit powers on or even indicates charging.

That I exactly mean

When my tablet is turned off for few hours, the battery fully discharge and I can't turn it on after, not it seems that charging I don't know happens with the battery

@e_v_rything1

When you say the tablet its off do you meant to say the screen its off or you actually power off the tablet? 

[e_v_rything1]

i mean everything the tablet don't have power doesn't works any more and don't charge 

i think i have to go to the service
