My ipod nano 5th generation won't turn on?

I have an ipod nano and i took it to the beach with me and it died and i didn't have my charger and I ended up leaving it at the beach (It stayed in the camper dead for like 3 weeks). When I went back to the beach i brought it home and i plugged it into my comp and it did nothing. It stayed off. I have done everything possible to try to turn it on, ive tried to reset it, hooking it to different computers with different chords and nothing is working. Has anyone had this problem and if so could you help me out?
