My 2 year old Lenovo IdeaTab A2109 just stopped working. The tablet is charged to 100%. When I power it up only "lenovo" appears on the screen. I've tried rebooting the system, wiping the cache partition, and did a wipe data/factory reset from the Android system recovery screen -- all with no results. When I connect the Tablet to my PC it is not recognized. Any suggestions what I can do to get it working, or should I put it in the recycle bin? Thank for your input!
