There is a row of keyboards that are out of order, and it is not good to get them

This situation on the computer is that the keyboard is broken, and there are three solutions:

1. Replace a keyboard.

2. When you need to use a failed key, call the system soft keyboard instead.

3. Repair the keyboard.

The keyboard repair method is as follows:

1. Check whether the keyboard is not plugged in, there is no connection between the keyboard and the computer, and observe whether the light on the keyboard is on, if the light on the keyboard is on, but the text and letters typed by the keyboard are still not visible on the computer, then the keyboard is broken, and you need to replace it with a new keyboard.

2. The failure of the computer keyboard is that the input text and letters and the text and letters displayed on the display screen can not correspond to each other, first check whether there is a problem with the switch key of the upper and lower case letters, whether it is stuck for any reason, if so, toggle the switch key with your hand to reset it. When a character is missing, it is possible that the dust on the keyboard or the debris dropped by snacks has entered the inside of the keyboard and caused a certain obstruction to the keyboard, as long as the dust and debris in the keyboard are cleaned up, you can use the keyboard again.

I have also encountered the same problem as lz, commonly known as string keys, and there are many reasons for this phenomenon: 1 The simplest problem is that the keyboard is broken, just change the keyboard. 2. The system, or any other software problem, needs to be reinstalled or all formatted.

3 is the voltage problem, which happened to be the problem last time. It is also possible to cause this phenomenon due to the instability of the voltage due to the failure of the power outlet. 4 is the virus.

See how lz solves it, I hope it helps you.

Causes and solutions

1. The main problem is the driver, the top row of keys is the function key, which should be used with FN;

2. The system is not right, install the genuine system.

3. The phenomenon that all the keys in a row of keys in the keyboard fail, but not all the keys fail is a typical failure of the internal circuit of the keyboard.

4. Restart your computer. The computer will run for a long time will cause the driver to fail, if the usual fn key is good, once in a while it fails, you can restart the computer to give it a try.

Keyboard maintenance

Nowadays, the use of computers is more and more, it is not only a tool for our work, but also a tool for our entertainment and leisure. Many people like to eat or smoke in front of the computer, which actually has a great impact on the keyboard.

If a large amount of soot falls into the keyboard keycaps, it can have a big impact on the feel of the keys. In addition, the tar in tobacco also has a strong corrosive effect on the film inside the keyboard, and long-term exposure to the corrosive environment will also reduce the feel of the keyboard and cause irreparable damage to the film.

The effects of eating food are even more self-evident, with larger particles of food debris making the keys more likely to get stuck, and extra care is taken not to spill drinks onto the surface of the keyboard.

If we sprinkle water on the keyboard, we should immediately turn off the power of the computer, and then unplug the keyboard, if there is no condition to disassemble the keyboard, we should also turn the keyboard upside down, pour out the water vigorously, and then dry the keyboard, make sure that the inside is completely dry and then try it on the computer, under normal circumstances, it can return to normal.
