[help!!]audiovox maesro battery and charger

help i just bought a used audiovox maestro pda last sunday from compusa (the only one they had) and it refuses to charge! it's been charging fine until yesterday. i live on long island in suffolk county so audiovox's headquarters aren't too far from me (actually like 10-15 mi) but i don't wanna have to have my mom drive me that far tomorrow since its snowing so hard but anyway what happens is it starts to charge like normal and the charging light is orange. then after an hour or so the light just shuts off and if i take it out of the charger it acts like the battery is completely drained! the screen fades out and i can't power it on! if anyone has experienced this problem and knows how to fix it so i don't have to call tech support or go to happauge. please please please tell me whats wrong. thx!!
