QuestionQ1

Hardware and Network Troubleshooting

A help desk technician inspects a laptop keyboard because a single key has stopped working. The technician checks the keyboard for debris. Which of the following actions should the technician do next to troubleshoot the issue cost-effectively?

Explanation

When a single key stops working after debris checking, replacing just the keycap is the most cost-effective troubleshooting step. A loose or misaligned keycap can prevent key actuation. Only if this fails should the technician consider more expensive repairs like switch replacement or full keyboard replacement.
