I got a mini heart attack today.
I got a new tablet somewhat recently. It’s an Ainol Novo 7 Venus. Today as I left work, I checked my e-mails on the tablet, it was working fine. As I got home the screen didn’t turn on, it remained dark. A little googling showed that others have seen the same problem. Which is nice, I only have to hard reset the tablet. The problem is that I couldn’t find it anywhere on the internet how to do that. So in case somebody else is looking for that too (or in the case I forget it):
To reset the Ainol Venus one must press the power and the volume up buttons together and hold them for a few seconds.
May it help to you too!
