If you have an iMac G5 computer with an internal Bluetooth module that isn't accepting input from your Apple Wireless Keyboard and Apple Wireless Mouse, here's how to troubleshoot the issue.
Here's an example of what a "Not Available" Bluetooth menu icon will look like:
If Bluetooth reports that it's "Not Available" and you are using an iMac G5 with an internal Bluetooth module, try these steps:
- Unplug all USB accessories from the computer.
- Shut down the computer (if necessary, by pressing and holding the power button on the back of the computer).
- Remove the power cord from the computer for one minute.
- Plug the computer back in and start it up, leaving all USB accessories disconnected. The Bluetooth keyboard and mouse should pair normally at this point—test them to be sure.
- Reconnect the USB devices.
If your Bluetooth keyboard and mouse worked as expected after start up, this indicates that one of your USB accessories is not compliant to the USB standard. You can do two things here—you can figure out which device is causing the issue, and you can follow our tips to keep the issue from happening again.
If you want to avoid this issue in the future, try these tips:
- Do not turn off your computer—instead, set it to sleep when you're using it. If you need to restart the computer, unplug all USB devices and wait until your computer has completely restarted and is ready before you reconnect them.
- Connect USB devices to a self-powered USB 2.0-compliant hub instead of connecting them directly to your iMac G5.
- Unplug all USB devices when you shut down your computer. You can plug them back in once the computer has restarted and the Desktop has loaded.
If you want to isolate which USB device is causing the issue:
- Plug in only one of your USB devices, such as a hub, and then restart your computer.
- If the issue occurs (your computer doesn't recognize your Apple Wireless Keyboard or Apple Wireless Mouse, and says that Bluetooth is "Not Available"), the connected USB device is the one that's non-compliant and the cause of the issue.
- If, however, the issue does not occur and your Bluetooth devices function normally, plug in one more USB device and then restart your computer again to see if the issue crops up. Keep doing this until the issue occurs again. Once the issue occurs, the last device you plugged in is the non-compliant one.
- Once you've isolated which USB accessory is not compliant, you can contact the manufacturer of that device for more assistance.
If this is not the issue causing your keyboard and mouse not to be recognized, check to make sure that Bluetooth is on. Check the Bluetooth menu icon in the menu bar; if the icon is dimmed, Bluetooth is off. (If there's no menu icon available, from the Apple menu, choose System Preferences, then click Bluetooth.) If you accidentally turned Bluetooth off, you can turn Bluetooth back on from its menu icon or from its preference pane.
If you checked and can confirm that Bluetooth is on and working, follow the steps in article 86496, "Apple Wireless Keyboard and Mouse: Troubleshooting Connection Issues."
