So, picked up a magic keyboard recently and have had the iPad sitting on it for a couple off weeks. Yesterday I noticed the Ipad was dead and so put it on charge. It didn't charge at all. Left it overnight, still nothing. Tried a 12v charger, no use. I suspect the magic keyboard has emptied the battery but often this only requires a bit of a kick from a higher voltage charger. I can see the battery with red line that indicates it is empty when I plug it in. Any ideas?
