The keyboard does not print the letters you press

The input device, or in simple words - the keyboard, is often susceptible to all sorts of accidental breakdowns and malfunctions. As a rule, most often they are mechanical, but sometimes it happens that they are purely technical. One of the most common problems is incorrect text typing. The user presses a certain key, and in response receives a completely different value, or does not receive any reaction at all. The reasons for this can be a variety of problems.

Why does the keyboard print the wrong letters?

The most common reason for an input device not to work correctly is a severely clogged keyboard. This especially happens after spilled tea, causing the buttons to become sticky. Even the ingress of ordinary water in a small amount can cause a similar effect.

However, water ingress is far from the only reason. Dust and various dirt can also cause such problems. Therefore, the first thing you need to do for the keyboard to work fully is to simply clean it thoroughly from dirt.

Despite the fact that the keyboard, like other small elements, receives the least amount of attention, it also requires good care.All that is needed from a person for this is timely cleaning of the housing, as well as maintaining cleanliness in the room.

This type of maintenance is the easiest and safest, because the user does not risk damaging the most important and expensive components of the computer, after which he will have to send all the equipment for repair.

To fully clean the keyboard, you need to disconnect it from the computer's power supply, after which you need to disconnect the buttons one by one and clean out the accumulated dirt under them. Despite the fact that this is a lengthy task, you need to remove the buttons as carefully as possible, since they can simply break under high force. If a person is afraid to carry out such a process on his own, just turn the keyboard over and gently knock on it; most of the dirt will fall out of the case itself.

Important! Before cleaning, you need to photograph the location of the keys, or prepare a corresponding image with them. It often happens that after completing the cleaning, people simply forget the order of the keys.

Common Causes

In addition to internal contamination, there are many reasons why the device writes the wrong letters. The most common of them are:

1. Additional keyboard – called using the command: FN + Insert. You press this combination and the operating system provides for the use of auxiliary characters. This problem will be relevant directly to laptop owners. Most often, it appears in a person when a special combination of buttons is accidentally pressed. To fix this, you need to re-execute the combination above.
2. Sticky keys – in 95% of cases, inexperienced gamers encounter this.When you press the Shift key multiple times, the system automatically blocks the use of the keyboard and displays the wrong letters. This was done directly for security purposes. You can disable this function in the “Control Panel” section, in which you will need to click on another section: “Ease of Access Center”. After which, the sticky keys setting will be available in the window that opens.
3. Problems with language settings - also a fairly common problem. In order for the layout to work fully, it is necessary to set in the “Languages” column the corresponding parameter in which the work will be carried out. Often, many people unknowingly install several languages ​​at once, after which a problem arises with regional management.

How to fix problems

If a thorough cleaning did not help, and the input device still does not work as it should, then you should urgently scan your computer with an antivirus program. The presence of malicious viruses is one of the possible causes of this problem.
If the result is positive, you need to check all the specified settings that were described above. If this does not help, then the next step is to check the device drivers. It often happens that they simply fly off due to an incorrect termination of the operating system. If this problem occurs, a warning window will pop up indicating that there are no drivers for the input device.

The last step, which will be more responsible, is checking the USB input. If this connector gets damaged, it will become a serious problem. Fortunately, there are several of them on the motherboard, so if one of them is free, the problem is solved.

When to contact specialists

It is worth noting that the keyboard itself is a consumable component of the computer. Regardless of the brand, model, or type of device, they all have a certain number of keystrokes that the manufacturers claim. With long-term use, repair will simply be impossible. Therefore, you will have to purchase a new device.

The only reason why you should contact a specialist is a damaged USB input connector. This connector is located on the motherboard, which is responsible for the entire functionality of the computer. In addition, it often happens that all the connectors may already be occupied by other devices, so the main solution will be a full-fledged repair.
