Plug Ipod into external power supply!!!!!
My friend just gave me an old 20gb u2 edition ipod and i plugged into my computer and it wanted to update it so i did. Now it wants me to plug it into an external power supply, so i tried using my usb adapter thing and that didn't work and i tried using two other adapters and a different cable that too failed, and now i don't know what to do, i cant do a full restore or whatever because the computer wont detect it and manually resetting it doesn't work, ive also tried the kinda wall charger that isn't an adapter. help???
