DS 821 MP3/MP4 won't operate

Brand new. Battery charged. Turns on but won't do anything. Screen shows zzzzzz (sleeping?) with arrow from MP3 to computer. Various buttons don't seem to activate anything. Manual is no help. Have connected to computer but that doesn't work either.

I have a rca M4304 mp4 and it will not turn on unless i plug it to the charder and when i unplug it it truns right back off

Ifthe MP3 player battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall. ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time. Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced.
