A malfunctioning keyboard can bring your productivity to a screeching halt. Whether keys are unresponsive, the entire keyboard is dead, or specific functions are acting up, it’s a frustrating experience. If you’re a Lenovo laptop user facing this issue, you’ve come to the right place. This comprehensive guide will walk you through various troubleshooting steps to resurrect your keyboard and get you back to typing in no time.
Understanding the Problem: Identifying Why Your Keyboard Isn’t Working
Before diving into solutions, it’s crucial to understand the potential causes behind your keyboard troubles. Identifying the root of the problem will help you narrow down the most effective troubleshooting methods.
Software vs. Hardware: Distinguishing the Cause
The first step is to determine if the issue is software or hardware related. A software issue might stem from outdated drivers, incorrect settings, or conflicts with other programs.
