No, it doesn't turn on...

If it does turn off, open the little door on the back of the calculator. Take the battery out, then plug the USB in. The calculator should turn on. Now put the battery in while the unit is running. Leave it for 10 minutes. Unplug again. Does it immediately turn off?

The calculator doesn't turn on with or without battery, the only way of life it presents is when entering in recovery mode using symb + reset
