Thank you for using Apple Support Communities!
It sounds like your iPod Classic will not turn on.
I found this article that addresses that issue specifically for you.
iPod won't turn on
Make sure the Hold switch is off
- Check to see if the Hold switch is on. It's located on the top or the bottom of iPod. When it's in the on position, you'll see an orange patch.
- To turn the hold switch off, slide it until you no longer see the orange patch.
- Press any button to turn on iPod.
Make sure the battery is charged
iPod won't turn on if the battery is empty. Instead, a low battery screen appears for about 3 seconds when you try to turn it on.To charge your iPod, connect your iPod to your computer's built-in 6-pin FireWire or high-powered USB port or connect it to the Apple iPod Power Adapter and plug the power adapter into an electrical outlet. Note: iPod models without a Click Wheel cannot be charged via USB. iPod shuffle requires a high-power USB port to charge. iPod nano and iPod (5th generation) can charge via USB or FireWire, but they require USB to sync with iTunes. If you're not sure what iPod model you have, click here.If you are connecting via USB and the battery is completely discharged, there may be up to a 30-minute delay before iPod powers up.

If iPod still does not turn on or appears to be "frozen" you may need to reset it. When you reset iPod all your songs and files are saved. Some customized settings may be lost.
Let the iPod battery drain
In rare cases, iPod might get into a state in which it needs to be drained completely before it can be reset. If iPod didn't turn on after you reset it, follow these steps:
- Disconnect iPod from all power sources and leave it disconnected for about 24 hours.
- Reconnect iPod to the Apple iPod Power Adapter or computer and reset it.
Update iPod's software
If iPod turns on after you reset it, use the latest version of iTunes to update iPod.
If you have tried the solutions above and iPod still won't turn on, check the following:
- Make sure iPod is the only device in your FireWire or USB chain. Disconnect everything but the mouse, keyboard, and your iPod, then see if it will turn on.
- Make sure you are using the FireWire or USB cable that came with your iPod, and that the cable is in good condition.
- Try connecting iPod to the built-in port of a different computer to see if that works. Note: If using a portable computer, make sure it is plugged in to a power source and that the lid or display is open. If the lid is closed the computer may go into either standby, sleep, or hibernation mode and iPod will not charge properly.
If you still can't turn iPod on after performing these steps, it may need to be repaired. You can arrange for repair at the iPod Service Website.
