What s going on with the keyboard and what should I do if the keyboard is garbled?

What happens when a computer keyboard fails?

Normally, we use computers to input various instructions and data into the computer through the keyboard to direct the work of the computer. The operation of the computer is output to the monitor, and the operator can easily use the keyboard and the monitor to talk to the computer, modify the program, control and observe the operation of the computer.

Next, let's take a look at the keyboard repair methods.

The operation is as follows: 1. Disassemble the keyboard. Note that when opening the keyboard, the button side (that is, the side we operate) must be down, and the circuit board up, otherwise the conductive plastic on each key will fall off one after another, causing trouble for your repair.

2. Open the circuit board. The circuit board is generally made of soft plastic film, engraved with key lines, with the best concentration of more than 97% alcohol cotton (more than 75% of medical alcohol cotton can also be, because I have applied, but it is best to use high concentration of alcohol cotton) gently scrub the road board twice. Take care of the key failure part of the circuit several times.

3. Check the conductive plastic of the failed part of the key. If there is a large amount of dirt on the upper area, it should also be scrubbed with alcohol. Assuming that the conductive plastic is damaged, then the author suggests that you can replace the conductive plastic on the infrequently used keys to the damaged part, although this kind of "tearing down the east wall and making up the west wall" can not make the keyboard play all the functions, but at least it can extend the life of the commonly used keys.

4. Sweep away the dirt in the inner corners of the keyboard. Tools can be brushes, small brushes, etc., but be careful to move gently.

5. Check whether the welding module has virtual soldering or desoldering. If you know how to use an electric soldering iron, you can do a repair soldering job. Of course, this step is only used for friends who can apply the soldering iron, and friends who can't apply it, please skip this step.

6. Install the keyboard. One thing to note here is that you must wait until the alcohol has evaporated.

There are three ways to recover from keyboard key disorders: First, check whether there is a foreign object stuck between the keys. If it is still out of order, you can press the unlock key numlock on the keypad to resume the normal output of letters and numbers.

If both of the above methods don't work, you can try restarting your computer.

If the keyboard button is not displayed, press the capslock key on the left side of the keyboard to see if the CAPS indicator on the keyboard is on.

If it can light up, it means that your keyboard hardware is most likely broken.

If it can't be lit, it means that your keyboard is either broken or has poor contact with the computer host, and the keyboard has no power supply.
