Keyboard Key Stuck

Explanation: A key was stuck on the keyboard as the system booted up. Some systems will detect this specifically, while others just give a generic “Keyboard error” in this situation. Some systems will produce a two-digit code when this error occurs, which tells you the scan code of the key that is causing the problem. This may let you correct it more easily.

Diagnosis: Usually this error occurs from trying to type on the keyboard while booting. If this is not the problem it is usually a keyboard problem.

Recommendation:

• Don’t type on the keyboard while the system is booting up.
• Troubleshoot the keyboard. Make sure that the keyboard is properly connected to the computer and/or reseat the plug into the back of the computer and then restart the system. If necessary, disconnect the keyboard and move it to another machine if possible to test it. If something has been spilled on the keyboard, discard it and replace it.
• Troubleshoot the keyboard controller by attaching a keyboard from another machine. If the problem goes away, it’s the keyboard, if it doesn’t, then there’s a problem either with the port where the keyboard attaches to the system or the keyboard controller on the motherboard.
• If none of the above resolves the issue, troubleshoot as a motherboard failure and replace the motherboard.
