Check the Number Lock

A common mistake that computer users often make is accidentally pressing the number lock button and not realizing it. To fix this, check to see if your computer has a number lock key. If so, either press the Num Lock key. If that doesn’t work, try the Shift key + Num Lock.

Switch Keyboard Layouts

Because most American and European languages use a form of the English alphabet, the keyboard language layouts vary by country. If you wish to use a specific layout or have found that your keyboard settings are programmed to a different default language, you can quickly fix this.

First, go into the control panel and access the “Time and Language” settings. Then go into the language settings, conduct a search and install a new default input language. Once the language is installed, you can click into the options for that language and set it as the laptop keyboard.

Run a Keyboard Troubleshooter

If your keyboard is typing a bunch of random letters and you think it’s glitching, you can try running a troubleshooter. To do this test (for Windows users), you can go into your settings and then into the “System” and then into “Troubleshooting.” Finally, find the options for the keyboard and press “Run.” After running this, it will tell you if you have any corrupted keyboard drivers.


Typing too much can cause damage to the tendons in your wrist. Be sure to take an adequate break if you have a job that requires a lot of typing.

For Mac users, go to your Apple menu and then into software updates to check if there’s a new OS to solve keyboard glitches. If there is, install it immediately.

STAT: In Europe, there are three main keyboard layouts: QWERTY, AZERTY, and QWERTZ. (source)
