I have had my thumby for about 9 months but I don't use it for a while and now it won't turn on. I charged it overnight and the furthest I have got is the logo appears but I can no longer have it show up in the code editor, the furthest I can get is have it make a noise when connecting to windows. 99% of the time it will just light up orange on the bottom and have nothing on the screen.
Try resetting your device, sometimes it is a software conflict. Or do you have any good solutions? 8)
