Check Connections Between Your Computer and an External Device

Details

When things are not working as intended, a common problem is that the cable between the computer and a device has become loose, broken, pinched, or disconnected. If you are having problems with your keyboard, mouse, printer, monitor, or any other peripheral, please do the following:

1. Turn off your computer.
2. Unplug the problem device.
3. Check the wire to make sure it is not damaged or pinched.
4. Plug it back in and make sure it is attached securely.
5. Turn the computer back on to see if the problem has been corrected.
