Troubleshooting : iPod Power problem

If you are experiencing suffer with your battery or overall power consumption, try these steps:

1. Be sure your power source is working. Plug another device into the same outlet to see if power is present. If you are charging your iPod touch using a computer's USB port, be sure it is USB 2.0. Most peripheral devices, such as keyboards, that offer USB ports typically do not have enough power to properly charge your iPod touch. Be sure to plug directly into your computer's USB port.
2. Test your cables. Try using another USB to dock connector cable with your iPod touch.
3. If your screen is signaling a low battery charge, plug your iPod touch into power and let it charge completely before disconnecting.
4. If your iPod touch will not power on, be sure to check all of the above steps. Plug your iPod touch into a power source and reset it. Hold the Sleep/Wake button on top and the Home button until the Apple logo or battery symbol appears. Once you see either the logo or the battery symbol, let your iPod touch charge until it is complete.
5. If your iPod touch does not power on after resetting it, try to restore it in recovery mode:
1. Connect a USB cable to your computer (but not your iPod touch).
2. Be sure your iPod touch is powered off. Press and hold the Home button while connecting the USB cable to your iPod touch.
3. Continue holding the Home button until the iPod touch starts up. You should see the "Connect to iTunes" message displayed on your iPod touch, and iTunes will alert you that it has detected your iPod touch is in recovery mode. You should then be able to restore your data from your last backup.

Finally, you should check for water damage to your iPod touch. The Liquid Submersion Indicator is located in the headphone jack of your iPod touch
