A technician is working on a laptop and a key on the keyboard is not responding as it should. What is a possible solution for this situation?

Using compressed air to clean the keyboard is a practical and effective solution for a key that isn't responding properly. Dust, debris, or crumbs can often become lodged under the keys, impeding their function. By applying compressed air, the technician can dislodge any particles that might be causing the key to malfunction without needing to replace any hardware.

This method is generally quick and does not require extensive disassembly of the laptop, making it a convenient first step in troubleshooting keyboard issues. In many cases, a simple cleaning can restore the functionality of stuck keys, avoiding the need for more invasive solutions like replacing the keyboard or reinstalling software.
