Important Note: iPods released since Sept 2008 (e.g. Touch 2nd Gen, 4th Gen iPod Nano and iPod Classic 120 Gigabyte, iPhone 3g and onwards) have an updated dock connector that means older revisions of speaker dock may not be able to charge these newer models of iPod/iPhone. Older docks should play music from these newer models with no problem.
The problem with charging is due to Apple removing support for 12v (firewire) charging on these new models of iPod/iPhone. Only 5v (USB) charging is supported on these new models. ..."

WHEN CONNECTED TO PC IT DISPLAYS OK TO DISCONNECT

HI there,

worst case scenario is that a circuit has broken inside. But your ipod will be under warrenty for a year from purchase.

Otherwise, leave the ipod to charge for a long time. Just leave it connected directly to the computer USB port despite not having any change in appearance. Also, don't connect it via a usb hub or through your keyboard. You will need to plug it into your computer directly.

You can also try entering DFU mode. Here is a great step by step guide to do that. http://iphonefreakz.com/beginners-guide/howto-dfu-mode/

Then restore the ipod and update the firmware. Make sure you have the latest version of itunes installed. By checking through software update.


I hope this helps,

Nathan.
