Why some keys on the keyboard suddenly failed

1.It has not been cleaned for a long time, and too much dust causes some keys to fail. This situation mostly occurs in mechanical keyboards, and if this is the reason, then you have to open the mechanical keyboard to clean up.

2.If there is a problem with the keyboard driver, you can update the driver to try it, update the method, first open the control panel, and then select the "keyboard" item.

3.After entering the keyboard properties window, select the "Hardware" tab, select "PS 2 Standard Keyboard" in the list, and click "Properties".

4.In the PS 2 standard keyboard properties window, select "Update Driver" in the "Drivers" tab interface and confirm.

<>6.After the update is successful, just restart your computer.

Generally, the keyboard is controlled by several transmission data cables inside the keyboard, which is why most keyboards can not be used together with many keys, 1qaz These keys are just on a data transmission line, your problem may be that the wire is broken or loose, you can take the keyboard apart, see if the small pressing sheet of the data cable connector (scientific name forgot) is loose.

But generally today's keyboards are almost disposable, especially some cheap keyboards, if you really can't change it, buy a better one, now more than 100 keyboards are good, hehe.

Hope I can help you, a friend of mine has a problem with your keyboard, his is the *963 of the keypad after the water penetratesIt's not easy to use.

This situation generally has nothing to do with the software, usually the keyboard circuit is wrong, and you haven't dripped water or drinks on the keyboard recently, or some dust has fallen on the keyboard, or your keyboard has been smashed by something, etc.

Or somewhere on the keyboard is stuck with dirt, hit a few keys to see if it can play normally;

Judging from the situation that it can be used after a sudden failure, it is that the key is stuck and has been connected, which is equivalent to you holding down the key all the time, which will of course affect your other operations.

First of all, it depends on whether you are using a wireless keyboard or a wired keyboard, if it is a wireless keyboard or whether the battery is dead, then try a new one.

The next thing to do is whether your keyboard is partially or completely out of order. Some failures are generally the desktop keyboard failure, that is, you inadvertently locked the keypad, click the "num lock" key to open it.

The keyboard is a kind of data input device used to operate the equipment, and also refers to a set of function keys arranged by the system to operate a machine or equipment.

The keyboard is also part of the musical instruments that make up the keyboard, and can also refer to the instrument that uses the keyboard, such as the piano, digital piano or electronic keyboard, etc., the keyboard helps to practice typing.

Keyboard shell, some keyboards use plastic concealed hook technology to fix the keyboard panel and base two parts, to achieve a metal-free screw-free design. So be careful when decomposing to avoid damage.

If the CPU is the heart of the computer and the monitor is the face of the computer, then the Qingyuan leather disc with key cavity is the mouth of the computer, which realizes the smooth communication between people and the computer. However, as the peripheral product that we have the most contact with, the role of the keyboard is mostly overlooked, which is of course inextricably linked to its slow development.

The keyboard is our most commonly used input device, in the process of computer use, the most used part is the keyboard, the computer keyboard key failure is a common problem, there are many reasons for the failure of the keyboard keys, how to solve this failure? Here is an introduction to the solution to the computer keyboard key failure.

Causes and solutions for computer keyboard key failure:

1. The keyboard interface is loose and the contact is poor, which will also cause the keyboard keys to fail, so you can plug and unplug the keyboard again. We can use a multimeter to detect whether the computer keyboard is damaged.

2. Check each key on the keyboard, it is possible that one keyboard is pressed, and if it does not bounce back, the other keys will not respond.

3. There is dirt on the circuit board or conductive plastic inside the keyboard, so that the two can not be connected normally, and it will also cause the failure of the keyboard buttons, and the specific solutions are as follows

1.Disassemble the keyboard.

Note that when opening the keyboard, be sure that the buttons are facing down and the circuit board is up, otherwise the conductive plastic on each key will fall off one after another, causing trouble to the repair work.

2.The circuit board is a film made of soft plastic, which is engraved with the key cables, and the circuit board is gently scrubbed twice with alcohol cotton (more than 75% medical alcohol cotton). The circuit of the keyboard key failure part can be wiped several times.

3.Check the conductive plastic of the failed part of the key, if there is too much dirt on the surface, it should also be scrubbed with alcohol. If the conductive plastic is damaged, it is recommended to replace the conductive plastic on the infrequently used keys with the damaged part, so as to at least extend the life of the commonly used buttons.

4.If there is dirt in the inner corner, you can use a brush, a small brush, etc., be careful not to push too hard, and move gently.

5.Check whether the welding module has virtual soldering or desoldering, if so, it is best to go to the repair shop and ask the maintenance master to help weld it.

6.Wait for the alcohol to evaporate and dry, and then install the keyboard.

The keyboard is not expensive, so much trouble is too much, don't put it and just change it to a new keyboard.
