it works while plugged in and thats it.

Hi @jacesmom2013 ,

If you have ensured that the battery is fully charged and it still only works when connected to a charger then there is a problem with the battery or the battery charging circuit in the player.

You state that I literally just bought this %#*@ thing.... What type of warranty if any, was offered by the vendor?

If there was a warranty given with the player and it is still valid, take it back for a refund

If there was no warranty or it is out of date and you wish to fix and keep the player here is a link to the ifixit Eclipse 180G2 MP3 Video Player Battery Replacement guide.
