4th Generation iPod Shuffle won't charge.

I have a fairly new 4th generation iPod Shuffle (8 months old) and it won't charge. The last time it worked I accidentally left it playing until the battery ran out of charge (if that helps identify a problem at all). From that point on the iPod has not been used, abused, or exposed to any elements. I tried to charge it yesterday, and nothing. The orange light will blink when connected to my laptop, and I can access the music and playlists stored on the iPod via iTunes. The charging icon will show up in iTunes and everything. But when I eject the iPod and unplug it, it is completely unresponsive as if there was no charge (the light won't even blink when you press a button). I've tried charging it for over 5 hours, and still nothing. Does anyone have any ideas of how I might get my Shuffle to start working again? I'd really appreciate it. Thank you!

Things I've tried:

-I've tried the "iPod reset" (no effect)

-Tried connecting to my macbook pro (my main computer, no effect)

-Tried connecting to a pc (no effect)
