Eva, in the absence of more information, my first gut feeling is that you have a non-functional battery. I believe it is time to change the battery. Make sure that you have a good USB cable. Check the dock connector and make sure that it is clean of debris and /or corrosion. Try to charge the iPod on a wall charger until you get a new battery. When you replace the battery take a good look at the connector for the battery, I have had issues with the connector coming right off the logic board. Anyhow, right now it is all academics, until you get power back. So my first suggestion is to change the battery. Good Luck and let us know how it is going.
