What usually causes a Nano 7 to be completely dead?
I found a secondhand nano 7 being sold for 20$. The description says it's completely dead and showed no reactions when it's charged, either using a pc or power adapter. Judging from the images It has no water ingress, no serious falls and minor cosmetic damage. Does a dead battery cause this, or is it a motherboard problem? Did anyone successfully repair a nano 7 with these symptoms? All the functioning iPod nano 7s I found typically cost around 40$, so I'd really like to know whether I can fix this.
Update:
Questa è una buona domanda?
