Keyboard Tester - Explanation

Our keyboard testing tool detects your keyboard keys and displays them on the virtual keyboard above. We have simplified this testing tool, so you can easily check your new and old keyboards, to detect damage. All popular browsers should be able to use this tool. The virtual keyboard above might differ from the keyboard that you have, but the test is still effective.

Please take the following steps, to make sure that your keyboard is fully functional:

  1. Start by pressing keys one-by-one. For example, start with the key "A".
  2. After pressing the key "A", the corresponding key on the virtual keyboard above should turn green (or orange when holding the key down".
  3. If the key on the virtual keyboard turned green, then that key is functioning correctly.
  4. Repeat the same process for every key on your keyboard.
  5. At the end of the keyboard test, all the keys should be green.

If some of the keys didn't turn green, it might be because your keyboard doesn't have that key, or your keyboard's key is malfunctioning. If you need help fixing common problems with your keyboard, please read the "Frequently Asked Questions" section below.

Frequently Asked Questions

Here are the answers to questions that we frequently get about keyboard related problems.


Why is my keyboard not working?

Here are some common problems with keyboard and their fixes.

Keyboard's keys are getting stuck

Keyboard keys getting stuck is a problem caused by either dust building up inside your keyboard or a sticky liquid under the keys. Most commonly, this issue gets resolved when you properly clean your keyboard. If you didn't know, you can pull the keys out of your keyboard to access the surface beneath your keyboard, making the cleaning process more manageable.

Wrong symbol/letter appears when pressing a key on the keyboard

It could be an issue with either your keyboard's drivers or your operating system's language settings. To download and install new drivers, head over to your keyboard manufacturer's website and look for your keyboard's model, or use an automatic driver finder, such as DriverBooster. Read the "How to change keyboard language" section below to fix your operating system's language settings.

Keys on the Numpad do not work

Keys not working on the Numpad is a widespread problem that is usually fixed by pressing the "Num Lock" key on the top-right side of your keyboard. The button "Num Lock" toggles your keyboard's Numpad area between two states: numeric state and alternative function state.

Keyboard is not responding at all

First of all, check if any of the keyboard's lights are on. If you cannot find any lights, then press your "CapsLock" key. If no lights have still turned on, then there might be an issue with either your cable or the keyboard isn't correctly connected to your computer.

It might be that the keyboard is damaged beyond repair, and it is time to buy a new keyboard.
