If a keyboard key isn’t working, there are a few things you can try to fix it. First, try cleaning the key. If that doesn’t work, you can try to reset the keyboard. If neither of those work, you may need to replace the key.
Cleaning the key
If a key is not working, the first thing to try is cleaning the key. You can do this by using a can of compressed air. Hold the can upside down and spray the key. You can also use a cotton swab to clean around the key.
Resetting the keyboard
If cleaning the key doesn’t work, you can try resetting the keyboard. To do this, unplug the keyboard from the computer. Then, hold down the “Fn” key and the “Shift” key. While you are holding these keys down, plug the keyboard back into the computer. Once the keyboard is plugged in, you can release the keys. This will reset the keyboard.
Replacing the key
If neither of the above methods work, you may need to replace the key. To do this, you will need to purchase a replacement key from the manufacturer of your keyboard. Once you have the replacement key, you can follow the instructions that come with the key to replace it.
