Are you frustrated with your Caps Lock key not lighting up when you press it? You’re not alone. Many computer users have experienced this issue, and it can be quite annoying, especially if you rely on the visual cue to know whether you’re typing in uppercase or lowercase letters. In this article, we’ll explore the possible reasons why your Caps Lock key is not lighting up and provide you with troubleshooting steps to resolve the issue.
Understanding the Caps Lock Key
Before we dive into the possible causes, let’s take a brief look at how the Caps Lock key works. The Caps Lock key is a toggle key that switches the keyboard between uppercase and lowercase letters.
