I have a green light when the shuffle is plugged in, but when I disconnect no lights no power

The led light should change colors

To charge the battery using your computer:
Connect iPod shuffle to a high-power USB port on your computer using the included iPod shuffle Dock. The computer must be turned on and not in sleep mode (some models of Macintosh can charge iPod shuffle while in sleep mode). When the battery is charging, the status light on iPod shuffle is orange. When the battery is fully charged, the status light turns green.
If you don't see the status light, iPod shuffle might not be connected to a high-power USB port. Try another USB port on your computer.

To charge the battery using an iPod USB Power Adapter If you do not have then you have to buy the same from Apple Store) 1 Connect the AC plug adapter to the power adapter (they might already be connected). 2 Plug the USB connector of the iPod shuffle Dock into the power adapter. 3 Plug the power adapter into a working electrical outlet. 4 Put iPod shuffle in the dock. You can disconnect and use iPod shuffle before it is fully charged.

Aug 07, 2009 - OK, I found the answer...there was a problem with the updated Windows service pack. I had to uninstall all applications(even in recycle bin) of all previous service packs including the new service pack 3. Then, went to Windows update and reinstalled the service pack 3 only and after installation, my ipod came to life! It was beautiful....Must be a compliant problem with the packs...I don't know!

It could be a few things.

1, The Charger is bad
2. The battery is completely dead
3. There is an internal malfunction that would require factory service.

While this may not help try plugging the charger into another computers USB port and dock it to see if anything happens.

I bought an Ipod shuffle 2nd generation yesterday, it charged all night and orange light was still blinking. Tried listening to songs and sometimes it would play but most times wouldn't. Took it back for exchange and same problem. Then I realized the problem is not with the USB plug or computer reoconizing ipod but in the docking itself. I applied pressure on the top side of docked Ipod and bottom of docking station and the computer recognized the Ipod. Release pressure and lose connection. The problem is that the docking station and earbuds do not connect with ipod and the fixes provided by apple doesn't address or fix this problem.
