I did not use my device (Kindle Paperwhite 7th generation) for some time. When I opened the case cover it was a blank screen with empty battery mark. I put it on charge, but after the over-night charging, the green light did not appear as an indicator that the battery is full. Device can no longer be turned on. Screen saver is on screen. I tried all possible combinations for restarting by holding power button for 8 or 40 seconds but nothing helps. Contacting Amazon chat support was no help either. When I connect device to laptop, computer recognized it but without showing Kindle storage as before.
Is there some way that I could save files from device drive at least?
