My iPod Shuffle Has No Light When Charging
The iPod shuffle is the smallest member of Apple's iPod family; unlike the rest of Apple's iPod devices, the shuffle lacks a screen that displays its battery level and charging status. Instead, the device features an indicator light as the only means of displaying its status. If this light is not lit while the iPod is charging, there is something wrong with the device.
Reading the Indicator Light
The indicator light on the top of the iPod shuffle displays the device's approximate battery level when it is being used. When the device is charging, it displays the device's charging status instead. If the light is solid orange and not flashing, the device is currently charging. If the light is solid green and not flashing, the device is fully charged. If the light is off, however, it can mean one of two things.
Sometimes, when the iPod shuffle's battery is completely dead, the battery indicator light may not come on immediately after connecting it to a computer for charging. If this is the case, plug the iPod into the computer via the USB connection cable that came with the device; let the iPod charge for several minutes. If after several minutes the iPod's battery indicator light is still not on, there is something else causing it to remain off.
Low-Powered USB Port
The iPod shuffle must be connected to a high-powered USB port in order to charge. If the device is connected to a low-powered USB port, it will not charge, and the battery indicator light will not light up. High-powered USB ports are those that are built into your computer. Low-powered USB ports, on the other hand, are those found on keyboards, non-powered USB hubs and other USB accessories. Connect your iPod shuffle directly to the USB ports on the computer. If the battery indicator light is still not on, there is something wrong with the device itself.
Restoring Your iPod Shuffle
Sometimes an error with the iPod device may cause its battery indicator light to stop turning on. In order to resolve this issue, you must restore the device to its factory settings. Restoring an iPod to its factory settings deletes all of the music on the device, so only restore your device as a last resort. Connect the iPod shuffle to the computer via the USB connection cable that came with the device and launch the iTunes application. Click on the iPod shuffle beneath the "Devices" heading and click the "Summary" tab. Click the "Restore" button and select the restore option that is right for you. After the iPod has been restored to its factory settings, follow the onscreen instructions to setup the device.
