Common Mechanical Keyboard Problems and their Solutions

Mechanical keyboards are machines and machines can be corrupted. Keyboards usually cause some common errors or problems and most of these problems can be solved easily.  Here I am going to discuss some common mechanical keyboard problems and there.

  2. Keys response slowly
  3. A wrong character output
  4. Repeated key register
  5. Jam keys
  6. Some keys are not working
  7. The keyboard is on but not working

1)     Mechanical Keyboard becomes Unresponsive

Sometimes while the keyboard is working fine but it becomes unresponsive suddenly. Not responding to any key strike. This kind of error is often caused due to overload on the keyboard or computer. You can fix it by unplugging the keyboard for a few seconds and then re-plug it into the computer. This method often works well.

2)     Keys Response Slowly

It means the keyboard is working fine but when you input keys on your mechanical keyboard it registers these keys very slowly in the computer. You are striking keys quickly but they are registering slowly at the computer while all the keys are registered after some time.

There can be two reasons for it. One is your computer hangs when you are striking keys. When a computer goes hang it responds slowly if you are inputting data it will save it slowly.

The second reason for it is that there is something false in the keyboard settings on your pc. Some computers offer customizing features for keyboards from there you can change the input speed of your keyboard. Go to computer windows settings and find keyboards and fix your issue.

3)     Wrong Character Output

It is a very dangerous problem. You are striking a key but the keyboard registers it with the wrong key which can be very hazardous for professionals. For example, you strike “K” but it is registered as “L”. There are also two reasons for it.

You replaced the wrong keycap. While cleaning or for other reasons you removed keycaps but when you reassembled these keycaps you forget the symmetry and replaced keycaps with other keys. In that case, identify the wrong character output keys and put the right keycaps.

The second reason is short circuits. Sometimes, the input board of keyboards becomes corrupted and it output of the wrong keys may be due to gathering carbon at the board. Clean your keyboard and its board which will result in positive.

4)     Repeated Key Register

Keys are registering multiple times while you strike it once. That is maybe due to the malfunction in the keyboard board. That causes short circuits or it is because keycaps do not go back automatically. Remove the keycap clean it and clean the board and switch under the key that is creating issues wait for a few minutes and put a keycap and test your keyboard.

5)     Jam Keys

 The key becomes jammed, hard to register, or even unable to register. If you are using your keyboard for a long time, then keys jam due to dust. Clean your keyboard or use hot air to remove dust particles that will resolve your problem.

Secondly, it is maybe by overuse of the keyboard. When you are using a keyboard there is a chance something goes under the keycaps that are making problems or maybe keycaps are melted due to some reason. Remove keycaps and here you will find your problem and its solution.

6)     Some Keys are not Working

Keys are not working, because you are unable to strike them completely. There are several reasons behind it like it is maybe due to dust or overuse of keyboard. Remove keycaps from not working keys and check if switches under the keys are working fine or is something in them. Remove it and test your keyboard.
