The keyboard is one of the most important input devices when we use computers every day. However, sometimes we encounter keyboard failure and cannot type. When the keyboard fails to input, how do we recover? This article will introduce several common methods.
First of all, we can check whether the keyboard connection is loose or disconnected. Sometimes the keyboard cable may become loose due to long-term use or accidental impact, causing the keyboard to not work properly. We can try re-plugging and unplugging the keyboard cable to make sure the connection is secure.
Second, we can try to restart the computer. Sometimes some temporary system errors may prevent keyboard input. By restarting your computer, you can clear these errors and get your keyboard back to normal again. During the restart process, the system will reload relevant drivers, which can help solve some keyboard-related issues.
If restarting does not solve the problem, we can try pressing the "Num Lock" key. Sometimes the Num Lock key on the keyboard may be accidentally turned on, causing the keyboard to be unable to enter characters. If the indicator light of the Num Lock key is on, we can press the Num Lock key to try to restore normal keyboard input.
In addition, some keyboards are also equipped with other special function keys, such as the "Fn" key. We can find these special function keys on the keyboard and press them to try to solve the problem of the keyboard being unable to input. These special function keys may sometimes be turned on accidentally, causing the keyboard to be unable to enter characters.
If none of the above methods can solve the problem, we can try to use an external keyboard or virtual keyboard to replace the original keyboard. By connecting an external keyboard to the computer and making sure it is working properly, we can verify whether the problem is with the keyboard itself or with the computer system. If the external keyboard can input normally, the original keyboard may be faulty.
In addition, we can also try to update the keyboard driver. Sometimes old keyboard drivers may be incompatible with the latest operating system, causing the keyboard to be unable to type. We can obtain the latest keyboard driver and install it on the computer by visiting the computer manufacturer's official website or a third-party driver update tool.
Finally, if none of the above methods can solve the problem of the keyboard being unable to input, we can consider contacting professional computer repair personnel or keyboard manufacturers for further repair or replacement. They will have more professional equipment and knowledge and can help us solve the problem of keyboard failure.
In short, when the keyboard cannot input, we can try to restore the normal operation of the keyboard by re-plugging and unplugging the cable, restarting the computer, pressing special function keys, using an external keyboard or updating the driver. . If the problem persists, we can seek professional repair help. I hope this article will help you solve the problem of keyboard failure.
