You are troubleshooting a laptop with multiple sticking keys that result in misspelled words while the user types. Other than several sticking keys, the laptop appears to be functioning properly. You have cleaned the keyboard with compressed air, but the problem persists. After removing one of the key tops, it becomes apparent that a liquid was spilled into the keyboard. Which of the following is the next step in resolving the issue of sticking keys? a. Replace the keyboard with a compatible keyboard. b. Disconnect and reseat the keyboard ribbon cable. c. Clean the keyboard keys with a contact cleaner. d. Replace the laptop system board and reseat all connections. ANSWER: c FEEDBACK: a. Incorrect. Replacing the keyboard may be the only option; however, for spills you can first try to use a contact cleaner on the keyboard’s keys and contacts. b. Incorrect. Reseating the keyboard ribbon cable can be an effective fix when the contacts become corroded or oxidized. Corrosion or oxidation will usually exhibit intermittent connectivity problems. The question states there was obvious evidence of a spill into the keyboard, which will require the keys on the keyboard to be cleaned with a contact cleaner or similar product. c. Correct. Contact cleaner can be used to clean a keyboard in which liquid has been spilled. Contact cleaners readily evaporate without leaving any residue. If the keys continue to stick, you will need to replace the keyboard. d. Incorrect. A system board replacement would be an option if the amount of liquid were sufficient enough to leak from the keyboard down to the system board. The question states that other than sticking keys, the system functions properly.
