Lenovo Ideapad A1 , dead, not working, no charge led
Solved! Found the solution in Lenovo's forum, A1 and A1107 Unbrick fix/full factory restore:


  There have been several instances of people having problems with A1 and A1107 devices. This guide explains how to fix any software issue, including those that "brick" the device, or stop it booting up at all, by restoring the tablet to a completely stock factory state. It can also be used to safely upgrade a Gingerbread A1 to Ice Cream Sandwich, by using the A1107 image that corresponds to the storage space that your device has.
