Troubleshooting Non-Responsive Keys on Your Laptop: Causes and Solutions

Are you experiencing unexpected issues with your laptop keyboard, where certain keys suddenly stop functioning? If so, you’re not alone. Many users encounter scenarios where specific keys become unresponsive, leading to frustration and interruptions in productivity. This article aims to help you understand potential causes for this problem and provide effective solutions to restore your keyboard’s functionality.
