27 mayo, 2021

Usually when your keyboard has a problem, record and it doesn’t work is notably in charge of letting you knowEither because you realize that none of its lights come on or because it starts beeping when you turn on the computer. But on other occasions it may have minor, less obvious and more difficult to detect malfunctions, also the mouse.

For example, sometimes it can happen that you get the feeling that a particular key does not seem to work, and you are not sure if you are the one who is pressing it wrong or if something is wrong with your connection. To clear up doubts in these cases You have at your disposal some tools with which to know if the keys of your keyboard or mouse are working as they should or not. Today we are going to propose seven of them, and we will end with some advice on how to act in each case.

KbTester, one of the best for Windows


And we start with KbTester, a small piece of French freeware specially designed to check your keystrokes. Its interface shows a full keyboard, and each pulse is marking with red on it What you do. When you see that you press a key and that it does not light up, you will know that it is because your equipment does not receive the keystroke.

The application is in French, although thanks to its very easy interface and its simple installation it is not a problem. It is designed for the Windows operating system, and is compatible with 64-bit and 32-bit versions so that nobody has problems when using it. It is just install and run.

Keyboard Test Utility doesn’t even require installation

Keyboard Test Utility

Keyboard Test Utility is a tiny tool whose main asset is that does not need to be installed, so you can put it in a USB and always carry it with you to test the keys of any computer. Its operation is the same as always, it shows the image of a keyboard and illuminates the keys that you are pressing.

While in the foreground disable function keys so that they do not interfere in the process, but its main advantage is that it has different visualizations for different types of keyboard. It also displays Microsoft virtual keyboard addresses and Scan Codes, the codes that the keyboard sends to the computer to indicate the key pressed., online and multiplatform


Since many of these tools are designed for a specific operating system, typically Windows, offers an online alternative to test the keyboard from any operating system. Its operation is simple, you open the web and you will get a pop-up window like the one in the screenshot, where you can write a text to test the keys.

It does not have too many functions, but offers the essential to know if all the keys on your keyboard work: when you press them they will light up on the screen. Its interface is also simple, another point in its favor, and the only problem is that it does not register combinations such as Ctrl + Shift, so you have to make sure to press them separately.

ScreenKey, exclusive for GNU / Linux


If you are a GNU / Linux user, you should know that you also have a native tool to test your keyboard, although it is quite different from the others. It is called ScreenKey and it will not show you the image of a keyboard and it will illuminate the keys that you press, but it will simply show on your screen each of the keys that you are using.

It is something like a subtitle, which in a way helps the application to do double duty. Yes, you can check on the screen if the computer registers a keystroke, but the application also appears as an interesting alternative if you are one of those who like to do video tutorialss, so that those who watch your videos know exactly which keys you are pressing during a process.

Aim400, test your mouse with minigames


A good way to test the performance of your mouse beyond knowing the keys that work, and everything while also testing your skills using it, it is the Aim400 minigame pack. It has been a highly recommended tool for years, since all its games are designed to put your reflexes, patience and mouse skills to the limit

In fact this, these are the three skill families on which all tests are based. You can practice aiming by clicking on balloons that change in size, your reflexes waiting for a balloon to change color and measure how long it takes to react, and your speed trying to explode balloons that appear and disappear at a devilish speed.

10FastFingers, test your keyboard by typing


Sometimes, although through these tests that we have seen it may seem that a keyboard works well, when it comes to putting it into practice you may notice small deficiencies. If you think it may be because of how you write, you can take your writing to the extreme with a quick typing test, and one of the best is 10FastFingers. Just go typing the words that appear to you and check that your keyboard is up to the task.

PassMark KeyboardTest, test keyboard and mouse

Passmark Keyboardtest

And we finished with PassMark Keyboard Test, which is possibly without a doubt the best program to test the operation of keyboard and mouse. It is a small program that weighs only 2.2 MB, and although it is priced at $ 24, it allows you to perform a 30-day free trial, enough to diagnose your peripherals.

The program shows the keyboard and mouse keys, and marks all the keys that you press to check that they work correctly. But besides that also allows you to test the keyboard LEDs, checks the movement of the mouse, the internal scan codes that are generated by the keyboard, and measures the typing speed of each user.

And what if the keyboard malfunctions?

Device administrator

Ok, you have used these programs and you have discovered that some of the keys on your keyboard do not work well. Now what? There are usually two possibilities, whether it is a software problem or a hardware problem, and for each of them there are different ways to try to solve it.

To download that it is a software problem, the first thing you should do is check your drivers. Each operating system has its device manager, and from there you should detect if there are any errors. In the event that there is not, you can also try uninstalling your current driver and reinstalling it just in case.

On the other hand, if you want to rule out that it is a physical error, try starting with a thorough cleaning of the keyboard, removing the keys or with a spray of compressed air. Who knows, maybe some crumb or something is preventing a key from being pressed correctly. If neither method works, you may have to get into service.
