Are you finding that the Caps Lock function of your keyboard has been reversed, and instead of typing a capital letter when engaged, instead it produces lower case letters? This problem often occurs after a keyboard has been unplugged whilst caps lock is on. This is actually a relatively common problem and can be fixed very simply, and in this article we will show you several possible solutions.
As the problem can occur when the keyboard has been unplugged with Caps Lock on, you can reverse this by pressing the shift key and then unplugging the keyboard once again. The keyboard should now function as expected with the Caps Lock key giving capital letters.
The Caps Lock function can also be reversed by pressing Ctrl+Shift+Caps Lock. You can revert it to normal by pressing this combination of keys again.
Check that the shift keys didn't get stuck.
