The main types of faults

It's no secret that these devices can have different shapes and additional keys with the corresponding functionality. Even take the same multimedia keyboard, which has a number of special keys at the top. Quite convenient, right?

But what should I do if a few keys stop doing their work or the whole keyboard is completely out of order? Without a doubt, you can buy a new device, but then you need to be ready to allocate 10-100 dollars for a new device. Why spend money if it is possible to bring the old device into working order? Prepare a soldering iron, a cross-head screwdriver, a tester and read the description of solving the problems for several cases.

Keyboard does not work completely

The most common cause of a breakdown is the interruption of the wiring connection inside the USB cable that we used to use to connect the input device to the computer.

Important! Most often, the gap occurs at the bottom of the keyboard itself or near the connectors for connection.

In order to determine the exact cause of the failure, you need to look for the operation of the LEDs, which are usually located in the upper right corner of the device. If the keyboard is "working", then all three lights should flash and go out when the computer restarts. If this does not happen, then you need to arm yourself with a multimeter( or any other testers) and ring the cable. To do this, you need to do the following:

1. Turn the device around, take a screwdriver and unscrew all the screws that hold the cover.
2. You will see a "film" in front of you with a lot of tracks. Also inside the keyboard is a printed circuit board and a small chip, which is a black drop.
3. The wire itself must be soldered to the board. We need to check the integrity of its connection with it. Take the multimeter, turn on the ohmmeter and call the desired area. You can also call the diode, which is much more convenient because of the sound signal.
4. If at least one "vein" is not phoned, then the replacement of the wire with a defect can not be avoided. You can try to bite off the wire cutters that part of the wire that is in the passage to the keyboard body.
5. If the wires are all right, then the case, most likely, in the chip itself. Then you just have to run to the store for a new one.
6. There is a possibility that the problem lies in the connector itself. Inspect it carefully for defects and align the bent legs with a thin hard object, if any defects are present.

With the return of the whole device to life figured out, but how to fix the button on the computer keyboard?

Keyboard works but not completely

Often we spill something on the desktop, and it's good if the liquid does not get on the keyboard from the computer, because if the keyboard gets wet, then a few buttons can refuse to work, or all at once. Also, partial mechanical damage can lead to partial damage, which sometimes happen accidentally. What to do in all these cases? Let's talk about each method of how to fix the keyboard in detail.

Spilled liquid

Your favorite tea was on the information input device? Immediately disconnect the gadget from the computer and wait for it to dry completely. If after that a few buttons came down, the following recovery method will help you:

• Uncheck all keys in order to open access to the space below them. Use for this purpose thin objects or loops made of copper wire.

Important! If you are a novice user, we recommend that you save a photo of the location of the keys to the computer so that the assembly can be completed without any problems.

• Set the keys aside and flip the keyboard. Now unscrew about a dozen screws holding the cover.
• Remove the cover and the film with the tracks, very gently wipe them with fleece, which should be moistened with alcohol. Allow the film to dry completely.
• Again, take an alcohol-soaked cotton wool and wipe the space under the keys.
• It remains to collect everything back and check the device for operability.

Mechanical effects

The device of the keyboard contains contact pads and conductive rubber. All of them are directly under the buttons of the keyboard. Sometimes small damage to the tracks can be repaired with the help of special compounds capable of conducting current. They are applied to tracks and bases of conductive rubber. But repair is not always possible if the device has been used for a very long time.

Important! Users who are fond of typing, can generally forget about its repair, since there is no sense in it. Rapid wear will return everything "in its place."

As you can see, there are ways to fix the keyboard or individual buttons on it. But still, this is not always possible. Therefore, be careful when working behind a laptop or PC, so you do not have to reap the rewards of your absent-mindedness.
