The main types of malfunctions

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

But what should I do if a few keys cease to do their job or the entire keyboard is completely out of order? Without a doubt, you can purchase 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 condition? Prepare a soldering iron, a Phillips screwdriver, a tester and read the description of the problem solution for several cases.

The keyboard does not work fully

The most common cause of failure is a broken wire connection inside the USB cable, which we used to use to connect an information input device to a computer.

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

In order to establish the exact cause of the failure, you need to look at 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 turn off during a computer restart. If this did not happen, then you need to arm yourself with a multimeter (or any other testers) and ring the cable. To do this, do the following:

1. Turn the device over, 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 microcircuit, which is a black drop.
3. The wire itself should be soldered to the board. We need to check the integrity of his connection with her. We take a multimeter, turn on an ohmmeter on it and ring the desired area. You can also ring the diode, which is much more convenient because of the sound signal.
4. If at least one “core” does not ring, then replacing a wire with a defect cannot be avoided. You can try to bite off the part of the wire that is in the place of passage into the keyboard body with the pliers.
5. If everything is in order with the wires, then the matter is most likely in the chip itself. Then you definitely have to run to the store for a new one.
6. There is a chance that the problem lies in the connector itself. Examine it carefully for defects and align the bent paws with a thin, hard object, if any defects exist.

The keyboard works, but not completely

Often we spill something on the desktop, and it’s good if the liquid didn’t get on the keyboard from the computer, because if the keyboard gets wet, then several buttons may fail or all at once. Partial damage can also be caused by strong mechanical stresses, which sometimes happen by chance.What to do in all these cases? Let's talk about each way to fix the keyboard in detail.

Spilled liquid

Was your favorite tea on the information input device? Immediately disconnect the gadget from the computer and wait for it to dry completely. If after this several buttons become unusable, the following recovery method will help you:

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

Important! If you are a novice user, we recommend that you save a photo of the location of the keys on your computer so that the assembly goes smoothly.

• Put the keys aside and turn the keyboard over. Now unscrew about a dozen screws holding the cover.
• Remove the cover and the film with the tracks, very gently wipe them with a cotton swab, which should be moistened with alcohol. Let the film dry completely.
• Again, take a cotton wool moistened with alcohol and wipe the space under the keys.
• It remains to collect everything back and check the device for operability.

Mechanical impact

The keyboard device contains contact pads and conductive rubber. All of them are located directly under the keyboard buttons. Sometimes minor damage to tracks can be repaired with the help of special compounds that can conduct current. They are applied to tracks and bases of conductive rubber. But repairs are 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, because there is no point in it. Quick wear will put everything back in its place.
