How to solve the problem of unable to enter letters on desktop computer keyboard

Which key to press when I can’t type on a desktop computer keyboard

With the advancement of technology, computers have become one of the indispensable tools in our daily lives. Whether for work, study or entertainment, the keyboard is an important tool for us to communicate with the computer. However, sometimes we may encounter a situation where the keyboard does not work properly, which causes great troubles to our work and life. So, when our desktop computer keyboard cannot type, which key should we press to restore its normal operation?

First of all, we need to confirm whether the keyboard is connected correctly. Sometimes, the keyboard's connections may be loose or plugged into the wrong place. We can first check whether the keyboard cable is firmly inserted into the keyboard interface on the back of the computer host. If the cable is plugged in correctly, the problem may not be with the connection.

Next, we can try pressing the "Num Lock" key or the "Caps Lock" key to check whether the keyboard is locked. Sometimes, the keyboard is locked by accidental operation, resulting in the inability to enter characters. In this case, we only need to press the corresponding lock key to unlock the keyboard and return to normal.

If none of the above methods solve the problem, we can try restarting the computer. Sometimes, some temporary system glitches may cause the keyboard to not work properly. Restarting the computer can clear these faults and allow the keyboard to restart.

If restarting does not solve the problem, we can try to enter the computer's device manager to see if there is a problem with the keyboard device. Click "Start Menu", select "Control Panel", find "System and Security", and click "Device Manager". In the Device Manager, find the keyboard device. If a yellow exclamation mark or question mark is displayed on the keyboard device, there may be a problem with the keyboard driver. We can try to update the driver or uninstall and reinstall the driver to solve the problem.

In addition, if we are using an external keyboard, we can try to plug the keyboard into other available USB interfaces. Sometimes, the USB interface may malfunction, causing the keyboard to not work properly. Plugging the keyboard into another USB interface can help us determine whether the problem is with the keyboard itself or the computer interface.

If none of the above methods solve the problem, we can consider connecting the keyboard to another computer for testing. If the keyboard works normally on other computers, the problem may be on our computer, which may be caused by a system failure or hardware failure. At this time, we can try to reinstall the operating system or contact professional maintenance personnel for repair.

In summary, when the desktop computer keyboard cannot type, we can follow the following steps to restore its normal operation: confirm whether the connection is correct, press the lock key to unlock the keyboard, restart the computer, and check the device manager , update or reinstall the driver, replace the USB interface, and test whether the keyboard works normally on other computers.
