Other reasons for non-functionality

Battery charger is not working

A typical problem, especially common with the Chinese representatives of electronics, which are often packed with terrible quality accessories. It will not power the tablet for one simple reason: the battery is powerful, the charger is not. Current flows with reduced strength or fluctuates.
