I have been using my IdeaTab A2107 for about a month now. This morning, after I had installed Splashtop and used it for half an hour, I closed the splashtop running on my PC, and the the tablet went blank. I have not been able to get it to start up again. I would hate to have to reinstall all the apps and download all the reference books I have loaded, however, I cant even get the start up screento display. When I press the power button, nothing happens, not even a vibration. Must I return the machine to the supplier or is there something else I can try?
