In the process of daily use of computers, we often encounter some problems. One of them is that the computer keyboard cannot type words, but only letters. This problem can be confusing and annoying because the inability to type text properly affects our work and life. So, what is the reason for this situation? How can we solve this problem?

First of all, we need to check whether the keyboard connection is normal. Sometimes, the keyboard's USB port may be loose or poorly connected, causing the keyboard to not work properly. We can try replugging and unplugging the keyboard to make sure it is firmly connected to the computer. If the problem persists, we can try connecting the keyboard to another USB interface to determine whether it is an interface problem.

Secondly, we need to check whether the keyboard driver is normal. In some cases, there may be issues with the drivers that prevent the keyboard from working properly. We can check and update the keyboard driver through the following steps:

1. Open the Device Manager. On Windows systems, you can find it by searching for "Device Manager" in the Start menu.

2. In the Device Manager, find the "Keyboard" option and expand it.

3. Right-click the name of the keyboard and select "Update Driver".

4. In the pop-up window, select the "Automatically search for updated driver software" option to let the system automatically update the keyboard driver.

If the system does not find an updated driver, we can try to download and install the latest driver from the keyboard manufacturer's official website.

In addition, we can also try to use the system’s own on-screen keyboard to enter text. The on-screen keyboard is a virtual keyboard that allows you to enter text with mouse clicks. On Windows systems, you can find it by searching for "on-screen keyboard" in the Start menu. Using the on-screen keyboard can temporarily solve the problem of being unable to enter text on the keyboard, and it can also help us determine whether there is a problem with the keyboard hardware.

If none of the above methods solve the problem, it is likely that the keyboard itself is malfunctioning. In this case, we can try connecting the keyboard to another computer to determine if the problem is with the keyboard. If the keyboard doesn't work properly on other computers, it's likely that the keyboard needs to be replaced or repaired.

To sum up, when the computer keyboard cannot input text and can only type letters, we can solve the problem by checking the keyboard connection, updating the keyboard driver, using the on-screen keyboard, etc. If the problem persists, it's likely that the keyboard itself is faulty and needs to be replaced or repaired. No matter what the situation is, we can take appropriate measures according to the specific situation to ensure that the keyboard can work properly and facilitate our use. .
