Keyboard test: online services, script, step-by-step instructions

There are times when you need to check the keyboard for functionality. If you use Microsoft Word, you will be able to make sure that only those buttons that are responsible for letters, numbers and some functions work. But the functionality of buttons such as F1 or F12 will not work. Online services that can show the status of all keys come to the rescue.

How to test the keyboard for functionality

Buttons must be checked in three cases:

1. When buying a new device.
2. If you purchased a used laptop.
3. If you suspect that some of them are out of order.

Most often, online services are used for verification. Using them is simple:

1. We go to a network resource.
2. Pressing the buttons step by step we look how the service reacts.
3. If clicking on them is fixed by the system, the color on the screen becomes different (most often blue).

Just by pressing it you can see which key the system could not determine, which means that it is out of order.

Attention! But there are buttons that fix the click on their own, that is, without human intervention. In these cases, the service will show that a particular one has been pressed several times. You can find the reason.

Keyboard Testing Online Services

To find out how services work, let's give examples of a few of them and find out how they work.

This service is in Russian. Using it is very convenient. Here you can check how the keys work, without downloading or installing additional programs on your computer. The advantage of this program is that in addition to the keyboard, it is able to check the status of the touchpad on the laptop.

1. We go to the service.
2. Launch the tester by clicking “Launch the Tester”.
3. A window opens showing the keyboard.
4. We press the keys sequentially.
5. If they turn green (and hear the sound characteristic of pressing), then it works.

PassMark KeyboardTest

Allows you to make diagnostics at a professional level. In addition to sticking and duplicating the driver, the correct codes and defects in the input panel. The disadvantage is that the program is paid. The principle of operation is similar to previous programs, the working key is painted in blue.

In addition to these, there are other services that can check the device for operability. Perhaps they are not so convenient and functional, but they are still in great demand.

How else can I check the keyboard for keystrokes

There is another way to test the keyboard for functionality - use the online script. It allows you to control internal codes when clicking on characters. In addition, sticky or duplicate buttons are tracked. To check through the script, do the following:

1. Startups script.
2. We go to the page and test settings. For comfortable work, Google Chrome is best suited.
3. You need to put the cursor in the main window.
4. Now you can press the buttons one by one.
5. The field shows the program codes corresponding to the pressed button.
6. If a malfunction is detected, a message appears in the main window.

This program is intended for testing at a professional level. Even advanced users will not understand the meaning of codes if they do not have programming skills. For such people, programs from the previous list are better suited.

Reference! If time allows, you can always use Microsoft word to check the most necessary buttons. But note, check the performance of the series F does not work.

Online services allow you to quickly check the status of keyboard keys. If during the verification process it shows that one of the buttons is malfunctioning, try cleaning the keyboard from dust. If the button breaks down, you can replace it or buy a new device.
