This can happen if the keyboard is unplugged from the USB port while a key is held down, or if a laptop or tablet is undocked while a key is held down on a keyboard connected to the dock through USB.
- Press the key that was held down once. If you do not know which key was held down, you may want to try pressing each key (Ctrl, Shift, Alt, and the Windows key) in turn.
- Use the touch screen or mouse to bring up the on-screen keyboard. Using the on-screen keyboard should reset the physical keyboard.
- Reboot the device.
