I bought this tablet from eBay, it came with windows only everything was fine until this morning the battery was dead so I plugged the tablet into a charging cable and when I came back after 30 min the tablet was still dead and I couldn’t turn it on, so I tried various combinations and the tablet would not boot up so I thought that I might let it charge for a while but then I noticed that the blue led is not coming up even though the tablet is charging for and hour on a 5v 2amp charger anyone got any clues?
