Troubleshooting your Apple USB Keyboard Step-by-Step

If your keyboard keys still aren't working after trying the steps in USB Basic Troubleshooting, try these steps, in order, until you've come to a resolution.

  1. Unplug all devices from your computer, including your mouse and keyboard, as well as your printer, scanner, cameras, iPod, external hard drives, and hubs. (Warning: Some devices, like iPods, may require you to perform steps before it is safe to unplug them.) If you have a hub, don't forget to unplug it as well.
  2. Plug your keyboard and mouse back into your computer firmly and securely. Take special care to make sure that the connector is completely in the port. (USB plugs fit into ports one way only, and won't plug in if you try to plug them in upside-down.)
  3. If that still doesn't work, try plugging your keyboard in to the other USB ports. Be sure to try them all. Check to see if the keyboard's Caps Lock light turns on when you press it, and try typing in one of your applications, such as TextEdit.
  4. If your keyboard works in one of your USB ports but not all, your computer may need service to resolve an issue with its USB port or ports.
  5. If your keyboard doesn't work in any of your computer's USB ports, it appears that your keyboard isn't functioning properly and needs to be replaced. You can order this part online. Order a replacement keyboard.
